This bug drives me a bit crazy. I get this usually when I try to use a quickfix or autocomplete. After this happens, it breaks code completion amongst other things... painful... not sure if this is SWT or JDT... eclipse.buildId=I20100805-1700 java.version=1.6.0_20 java.vendor=Apple Inc.

Looks like we're getting a GC on a window that isn't visible yet, but we defend against that on Control.java:1879 by forcing it to be created. The next time this happens can you check for a log message in Console.app?

Stumbling around for ideas here.... are you using Spaces with Eclipse? A google search hints that's one way to cause this to happen. I'm also looking into why the memory consumption is considered to be so large here that we need to do deferred creation.
(In reply to comment #2) > hi, > > this is from the console.app at the time the exception occurred: What version of the OS and which Eclipse build are you using? Thanks in advance.

Thanks in > advance. this is Snow Leopard 10.6.6, uname prints: Darwin zregvart 10.6.0 Darwin Kernel Version 10.6.0: Wed Nov 10 18:13:17 PST 2010; root:xnu-1504.9.26~3/RELEASE_I386 i386 eclipse version from about is: Eclipse Java EE IDE for Web Developers. Version: Helios Release Build id: 20100617-1415 swt plugin is version: 3.6.0.v3650b if by Spaces you mean OS X multiple workspaces tech, then yes, extensively, but eclipse is situated on fixed space (set in preferences) I also have Cinch (http://www.irradiatedsoftware.com/cinch/) installed, that in previous version had an issue with iTunes (caused it to crash), and could be somehow related (http://getsatisfaction.com/irradiatedsoftware/topics/cinch_causes_itunes_9_1_to_crash_when_in_list_mode_w_column_browser_at_top) thanks, and sorry for the late reply
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
