Description Chol CLA 2010-07-07 05:55:35 EDT 
Build Identifier: 20100617-1415

If I type in "bool" and hit CTRL+SPACE for autocompletion, Eclipse freezes and the screen turns gray.

I'm using Ubuntu Lucid 10.04 x64 with Helios EE x64 and tried both "OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-0ubuntu1)" and "Java(TM) SE Runtime Environment (build 1.6.0_20-b02)".

I will add several logfiles, as I tried all stack trace methods which were described in the wiki deadlock page.

Reproducible: Always

Steps to Reproduce:
1. Type in "bool"
2. Hit CTRL+SPACE

Looks like the AST problem. Could also be Texlipse misbehaving.
Comment 7 Dani Megert CLA 2010-07-07 06:34:24 EDT 
This is a bug in the Texlipse plug-in: it accesses the UI thread inside the reconciler:

   java.lang.Thread.State: WAITING (on object monitor)
	at java.lang.Object.wait(Native Method)
	- waiting on <0x00007fa1de85e4d0> (a org.eclipse.swt.widgets.RunnableLock)
	at java.lang.Object.wait(Object.java:502)
	at org.eclipse.swt.widgets.Synchronizer.syncExec(Synchronizer.java:186)
	- locked <0x00007fa1de85e4d0> (a org.eclipse.swt.widgets.RunnableLock)
	at org.eclipse.ui.internal.UISynchronizer.syncExec(UISynchronizer.java:150)
	at org.eclipse.swt.widgets.Display.syncExec(Display.java:4294)
	at net.sourceforge.texlipse.TexlipsePlugin.getCurrentWorkbenchPage(TexlipsePlugin.java:249)
	at net.sourceforge.texlipse.TexlipsePlugin.getCurrentProject(TexlipsePlugin.java:221)


The reconciler must not access the UI thread. Please report the bug there.

Thanks, uninstalling TeXlipse solved the problem for me. But I don't understand why TeXlipse fiddles with .java files, shouldnt' it only activate on .tex?

They probably installed the spell checker on any file with content type 'Text' and 'Java' inherits from that. If there's an option to disable spell checking in TeXlipse, then that should also solve your issue. Disabling spelling all over (General > Editors > Text Editors > Spelling) should also do the trick.
