Eclipse 3.2 One of my colleagues had a crash today after copying and pasting some very long text from one editor to another. Unfortunately he doesn't remember which editor it was but probably the WTP HTML editor. But the interesting thing is that not any of the traces point to the specific error but to JFace text. Thus, I'm reporting it here. The error log is very long but it's all related to that error. Looks like Eclipse was in some loop and got unstable et all. After the crash the workspace was corrupted and I had to assist him via VNC to restore it properly. As far as we could tell after that, no project file had been damaged.
Created attachment 46434 [details] Log file from the session This is the log file from the complete crashed sessions. It all starts with a tiny message. !MESSAGE "Paste" did not complete normally. Please see the log for more information.
The log says: eclipse.buildId=unknown Are sure it was R3.2? Marking as INVALID since the initial NPE at: org.eclipse.jface.text.DefaultPositionUpdater.update(line 227) is not possible to have with Eclipse SDK. Possible reasons: - incorrect install, e.g. copied new build over existing install - JIT bug - bug in another plug-in that sets fOriginalPosition to 'null' (not very likely)
(In reply to comment #2) > The log says: eclipse.buildId=unknown > Are sure it was R3.2? Yes I am. It's our internal distribution with some branding. :) Note that eclipse.buildId is just a property read from config.ini which is intentionally not set in our distribution. > Possible reasons: > - incorrect install, e.g. copied new build over existing install > - JIT bug > - bug in another plug-in that sets fOriginalPosition to 'null' (not very > likely) As reason one can be excluded (I told and force the guys to always rename an existing directory and unzip the distribution into an empty directory) it must be either a JIT bug or a problem in the other editor. :( Daniel, can you do something to prevent another plug-in from setting fOriginalPosition to null?

This bug seems to be still around. I am having this problem with Eclipse 3.3. The original bug report was not for Eclipse 3.3, should I therefore rather open a new bug tracker entry for this? Distribution: Eclipse for RCP/Plug-in Developers - Linux (152 MB) Additional Plugins: only Polarion Subversive SVN 1.1.7 (not sure if I also had to install some data tools plugins due to subversive plugin dependencies) OS: Linux 2.6.22.5 @ Debian Etch Context: I was editing a plain text file with the eclipse text editor and got this exception while typing. I've encountered the exception 3 or 4 times so far. But I was not yet able to reproduce it. Last time it happened while pasting data into the same text file (also using the text editor, stack trace was identical).

versions. But it's basically a plain Eclipse RCP install + Subversive (incl. dependencies).
You can continue to paste your info here. So far we have no steps and hence there's not much we can do.
But if some other code is indeed setting fOriginalPosition to null, wouldn't an additional guard which reinitializes fOriginalPosition, if needed, be a working quick fix? i.e. change: > fOriginalPosition.offset= fPosition.offset; to: > if (fOriginalPosition == null) > fOriginalPosition = new Position(0, 0); > fOriginalPosition.offset= fPosition.offset; (though moving the check above the for loop would probably be better) in: org.eclipse.jface.text.DefaultPositionUpdater.update(DefaultPositionUpdater.java:233) And fPosition can't be null here either? Are these values ever accessed concurrently by multiple threads?
We don't add guards if you don't know why the NPE happens. This just hides an error at some other place.
The error does seem to occur quite often lately, maybe I'll be able to reproduce it in the long run. It happened again today and I noticed that there are some mylyn related exceptions in the error log, could they be related to this issue?

Hard to say but I doubt it.
Recently got a new exception which might be related to this problem. It's the first time I've seen this exception though. eclipse.buildId=I20070621-1340 java.version=1.6.0_02 java.vendor=Sun Microsystems Inc.

Ok, I was finally able to catch the exception in a debugger run. It seems as if it is not fOriginalPosition that is null, but one of the elements of the Position array which is returned by org.eclipse.jface.text.IDocument#getPositions(java.lang.String). I don't quite see how that could have happened though. If I understand correctly, there shouldn't be any concurrency issues when using a SynchronizableDocument. But a race condition is the only explanation which I can come up with right now though. However, when looking at the SynchronizableDocument implementation it will only synchronise access, if there exists a lockObject. But in this stack dump, lockObject is null. Which means that no synchronisation code is executed. If the execution of AbstractDocument's org.eclipse.jface.text.IDocument#getPositions(java.lang.String) implementation would be interrupted between these two lines > Position[] positions= new Position[c.size()]; > c.toArray(positions); by another thread which removed an element from the positions list for that position category, that would result in the failure described in this bug report. So is the real defect here that the text editor fails to correctly set a lock object for the document then? Here is some of the data which I extracted from the debugger. Unfortunately when catching an NPE it stops at the end of the method, and the Position array value is thus no longer accessible. I tried using a conditional breakpoint but it was way too slow (~30sec delay per key press) to be of any use.

>The error does seem to occur quite often lately, We've never seen this here. I suspect some other plug-in might cause this.
Well, as you can see I do not have any 3rd party plugins installed besides the polarion subversive SVN client. So you believe that the polarion SVN client is the cause for this failure? *** Features: org.eclipse.cvs (1.0.0.v20070606-7C79_79EI99g_Y9e) "Eclipse CVS Client" org.eclipse.cvs.source

>Well, as you can see I do not have any 3rd party plugins installed besides the Not true - there's tons of stuff you have installed on top of the Eclipse SDK (EMF, WTP, Mylin, etc.).
Ah, ok. A misunderstanding then. I didn't count them as 3rd party plugins as they are all eclipse projects. Wouldn't the eclipse bugtracker be the correct place for this issue then? No matter which of the eclipse plugins caused it? Anyway, I'll try if I can reproduce the problem with a vanilla eclipse install.
> Wouldn't the eclipse bugtracker be the correct place for >this issue then? No matter which of the eclipse plugins caused it? Sure, but as you can see there are many different components. I did not say it is not a Platform Text bug but so far I can't reproduce.
I've written a Junit4 test case which reproduces the failure on my system (it may take a long time, it is basically a large number of edits with random delays). I can reproduce the failure with the following pretty minimal eclipse configuration. So it doesn't seem to be related to any of the extra plugins. *** Features: org.eclipse.jdt (3.3.0.v20070606-0010-7o7jCHEFpPoqQYvnXqejeR) "Eclipse Java Development Tools" org.eclipse.sdk

>I've written a Junit4 test case which reproduces the failure on my system (it >may take a long time, it is basically a large number of edits with random >delays). Good, that will help us to reproduce the bug then. Please attach it here. Also, "long time" depends on your view on things - are we talking about seconds or hours?
Created attachment 79969 [details] JUnit4 test case which reproduces the failure on my system - READ THE COMMENT This is a small plugin project which contains a JUnit4 test case that reproduces the failure on my system. Notes: - English (could be any language but German) spell checking needs to be enabled (you need to see the red lines below most of the words in the text) - The defect is a race condition. The test case tries to create the failure condition by doing an endless number of edits with random delays. On my system it can take between one second and a couple of hours to reproduce the failure. Most of the time I get a failure within the first 15 minutes though. - This was tested on a dual-core system. Things might be different on a single-core system.
Another note about the test case. I just tried it with 3.3.1 (M20070921-1145) and it will be very unlikely to reproduce the bug on such a system because the number of spellcheck suggestions is now limited. However, if the limits on the spelling preferences page are increased as much as possible, the test case will still reproduce the issue.
3.3.1.1 still has this issue. I'd suggest changing the status of this entry from RESOLVED to REOPENED. The problem here is that a file opened in a TextEditor will lead to a SynchronizableDocument which does not have its lock object initialised. I am not familiar with the IDocumentProvider code base but it seems that for a java file, CompilationUnitDocumentProvider.createFileInfo(Object) calls TextFileDocumentProvider.setUpSynchronization(FileInfo) which in turn calls SynchronizableDocument.setLockObject(Object). For a text file on the other hand, TextFileDocumentProvider.createFileInfo(Object) never calls TextFileDocumentProvider.setUpSynchronization(FileInfo) and thus SynchronizableDocument.setLockObject(Object) is never called. Is there any reason why a text document should not be synchronised? As CompilationUnitDocumentProvider extends TextFileDocumentProvider, changing this in TextFileDocumentProvider might be a bit problematic. But a new sub-class, i.e. SynchronizableTextFileDocumentProvider, could be used for the TextEditor, couldn't it? I understand that this might not be high on the priority list. However, we're still experiencing multiple TextEditor crashes per day, which are most likely all caused by the fact that the documents are not being synchronised. Thanks a lot. MfG H. Meyer

I got this too today: 1. Open text editor with 'Faust - Der Tragoedie erster Teil' 2. Enable spell checking with English dict 3. Set max spell errors to 9999 4. Show spelling errors in vertical ruler (and only there) 5. Now start typing, saving, typing new lines, saving, ... like a maniac for a few seconds, exception is drown and editor is unusable Also got this: java.lang.IndexOutOfBoundsException: Index: 9469, Size: 9469 at java.util.ArrayList.RangeCheck(ArrayList.java:546) at java.util.ArrayList.get(ArrayList.java:321) at org.eclipse.jface.text.AbstractDocument.removePosition(AbstractDocument.java:1003) at org.eclipse.core.internal.filebuffers.SynchronizableDocument.removePosition(SynchronizableDocument.java:203) at org.eclipse.jface.text.AbstractDocument.removePosition(AbstractDocument.java:1015) at org.eclipse.jface.text.TextViewer.setMark(TextViewer.java:4591) at org.eclipse.ui.texteditor.IncrementalFindTarget.beginSession(IncrementalFindTarget.java:305) at org.eclipse.ui.texteditor.IncrementalFindAction.run(IncrementalFindAction.java:100) Looks like we have a synchronization issue

(In reply to comment #26) > *** Bug 211509 has been marked as a duplicate of this bug. *** Hi Daniel Reading what the other had seen on their cases, i try to edit other program, shorter than the one how has the issue (This one has more than 4000 line of code) and let me work normally, then i disable the spell cheking function on the editor, a went back to the firsto program and let me work as well, i think maybe the spell cheking function when detects too many words mispelled, can handle it and blocks the editor. For now i can work like this, because i don't need the spell cheking function, (my work is in cobol and i dont have a compiler on my pc). Thanks for the support, if you find some way of fix this, please let me know. Thanks again Iván Rojas

Could not reproduce using steps form comment 21 and comment 25 on my single core machine. I then modified the priority of threads randomly and can now easily reproduce.

Does this seem to be an issue with the lock object initialisation in TextFileDocumentProvider after all? Or did you find a defect elsewhere? Is this likely to be fixed in 3.4? Greetings H. Meyer
The fix is in HEAD. There were two issues: the lock object not being set in some cases (most subclasses did this so far) and a hole when the annotation model was taken from the file buffer and not from createAnnotationModel(IFile).
