Since bug #38682 seems to be "resolved" in version eclipse 2.1 I tought it would be a good thing to reopen it for 3.0.1 Here's the comment I wrote for #38682 ---------------- I'm running eclipse 3.0.1 on RH AS3 Build id: 200409161125 using java version 1.4.2 Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2) Classic VM (build 1.4.2, J2RE 1.4.2 IBM build cxia321420-20040626 (JIT enabled: jitc)) Last friday I closed eclipse before leaving the office, this morning when I came to work, I started eclipse as usual however I got a popup that pointed an error, and that I had to check my .log file. To make my eclipse start again I had to move .metadata/.plugins/org.eclipse.core.resources/.snap out of the way However, after eclipse restarted all my projects were gone and I had to import them one by one. Luckily I did not seem to have lost any java code. But I lost two hours finding the problem and rebuilding my workspace. here's an extract of my .log file: !SESSION Feb 28, 2005 12:52:40.838 ---------------------------------------------

So your previous session had exited normally - not frozen or the process terminated from the Task Manager? Unfortunately it looks like the startup error is masked in this case by an error in shutdown. PluginActivator.start catches the exception on startup, and then calls Plugin.shutdown(). If shutdown() throws a second exception, the first exception (the real cause of the failure) is lost. We should fix the error reporting here to make sure failure information is not lost.

What should I do next time something like that happens again, so that you can have more debug information ? What should I not do so I don't screw the logs / state of eclipse when the bug occurs. Thanks for the reply. Tony
The samething happened again this morning... Is there something I can do to help to debug ?

Eclipse died for me an hour ago in similar fashion. It will not restart due to java.lang.NoClassDefFoundError: org/eclipse/core/resources/IProject. However, the start of the problem was a crash which happened while opening a project. The log extract below shows the original crash and then the failed restart attempt. !ENTRY org.eclipse.core.runtime 4 2 2005-05-05 11:50:07.828 !MESSAGE An internal error occurred during: "Refreshing workspace". !STACK 0 java.lang.IllegalArgumentException: Element not found: /sa_slm.oss/BuildArea/core/intermediate/classes/sa_slm.sla_mgmt/com/comnitel/slm/sla/slam/util/veto. at org.eclipse.core.internal.watson.ElementTree.elementNotFound(ElementTree.java:373) at org.eclipse.core.internal.watson.ElementTree.createElement(ElementTree.java:282) at org.eclipse.core.internal.resources.Workspace.createResource(Workspace.java:731) at org.eclipse.core.internal.resources.Workspace.createResource(Workspace.java:765) at org.eclipse.core.internal.localstore.RefreshLocalVisitor.createResource(RefreshLocalVisitor.java:82) at org.eclipse.core.internal.localstore.RefreshLocalAliasVisitor.createResource(RefreshLocalAliasVisitor.java:34) at org.eclipse.core.internal.localstore.RefreshLocalVisitor.synchronizeExistence(RefreshLocalVisitor.java:220) at org.eclipse.core.internal.localstore.RefreshLocalVisitor.visit(RefreshLocalVisitor.java:292) at org.eclipse.core.internal.localstore.UnifiedTree.accept(UnifiedTree.java:88) at org.eclipse.core.internal.localstore.FileSystemResourceManager.refreshResource(FileSystemResourceManager.java:632) at org.eclipse.core.internal.localstore.FileSystemResourceManager.refresh(FileSystemResourceManager.java:619) at org.eclipse.core.internal.resources.Resource.refreshLocal(Resource.java:1257) at org.eclipse.core.internal.refresh.RefreshJob.runInWorkspace(RefreshJob.java:134) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:37) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:67) !SESSION 2005-05-05 11:52:09.566 ----------------------------------------------- eclipse.buildId=I20050219-1500 java.version=1.4.2_08 java.vendor=Sun Microsystems Inc.

For recovery, this suggestion posted by Sven_Eu at http://howardlewisship.com/blog/2004/10/worst-eclipse-crash-ever.html seems to have worked for me: "I deleted the files \.metadata\.plugins\org.eclipse.core.resources\.snap and \.metadata\.plugins\org.eclipse.core.resources\.root\.markers.snap and I could start eclipse with my workspace and its projects preserved properly. Everythng seems to work as it did before"
I think this can be reproduced by calling refreshLocal on a file whose parent folder does not exist. The test for this in the refresh local visitor is only done for non case-sensitive file systems: if (!CoreFileSystemLibrary.isCaseSensitive()) { Container parent = (Container) target.getParent(); if (!parent.exists()) { refresh(parent); I don't know why it is not done on case-sensitive file systems. I should be able to create a test to reproduce this.
Ewan, from your stack trace it looks like you are using linked resources. Can you briefly describe your project structure, including what linked resources are pointing where? If you like, you could attach the .project file for your projects that will contain this information. Also, are you using unix sym-links anywhere in your project? I am trying to reproduce your failure based on the information in the log - if I can get a reproducible case I'm sure a fix would not be far behind. Comment #6 was a false lead. RefreshLocalVisitor#createResource also creates missing parent nodes as necessary.
Adding Ewan to CC - can you respond to comment #7?
Created attachment 20777 [details] .project file .project file as requested.
(In reply to comment #8) > Adding Ewan to CC - can you respond to comment #7? I attached the .project file. Just be way of explanation, in every Eclipse project I work on, I add a folder called "BuildArea" as a linked resource. This links to a folder on my local machine (PC) which contains jars, configuration, src-zips, etc for the product I am working on. Everything I work on is a sub-project of the product.
Finally, regarding unix links, I work on and build to a windows pc, but I access src on a unix box mounted via samba. Files not checked out of source control are links.
After much effort I was unable to create a reproducible test case. I will leave this open but unfortunately will probably not be able to fix in time for 3.1.
Just happened to me again... It crashed suddenly in debug mode, then I started to restart... looks like the same class not found error... We are running Eclipse off the network, might be an issue. -Tony Here's the log !SESSION May 12, 2005 19:11:48.577 --------------------------------------------- eclipse.buildId=M200409161125

I just want to clarify the information in this bug. In Tony's case, the actual cause of the failure is being obscured by a follow-on exception that occurs during shutdown after the first exception. Because of this, I have no idea what is happening, or whether it is the same as Ewan's case. In the 3.1 stream builds (which Ewan is using), this secondary failure has been fixed and the original failure should be more apparent. I am exploring minimally adding better exception handling in Ewan's case to allow startup to proceed. I can only hope that Tony's case is the same and fixing one will fix both. Tony, if you get a chance to try a 3.1 stream build I would be able to confirm whether your problem is the same or not.
I should add that in this situation, sometimes deleting the file workspace/.metadata/.plugins/org.eclipse.core.resources/.snap has been known to make the startup problem go away. It would be useful to know if this works for either of you.
(In reply to comment #15) We have had a case of another user reporting similar problem as Tony and your workaround has got him back up and running.
(In reply to comment #15) The link in comment #5 suggests that deleting \workspace\.metadata\.plugins\org.eclipse.core.resources\.snap alone results in loss of projects from workspace. I can't verify that. But I did use the full suggested workaround which is to delete \workspace\.metadata\.plugins\org.eclipse.core.resources\.root\.markers.snap also and it worked just fine.
I just had a similar problem with 3.1m7 on PC/WinXP: https://bugs.eclipse.org/bugs/show_bug.cgi?id=95306 The workaround did not work for me as there's no \workspace\.metadata\. plugins\org.eclipse.core.resources\.snap or \workspace\.metadata\.plugins\org. eclipse.core.resources\.root\.markers.snap in my workspace.
Created attachment 21282 [details] Patch to org.eclipse.core.resources Even though we haven't created a reproducible test, this patch should fix the problem. - Changed RefreshLocalVisitor to ensure the parent resource exists before refresh ing a resource. Previously this code ran inside an if (!caseSensitive) block, so it did not run on Linux. - If refresh fails during Workspace.open, log the failure but continue with startup. In the worst case, this will ensure any problems in the refresh code do not cause startup to fail.
DJ, I'd like to consider this fix for RC1
+1 for RC1
I have released the fixes in the patch on comment #19.
I have also released this fix to the 3.0.x stream. A patch that can be applied to either Eclipse 3.0.1 or 3.0.2 is available here: http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/platform-core-home/downloads.html If anyone still has a broken workspace in 3.0.x, running with the patch should allow you to startup. Please report results here if you do this so we can verify the fix.
