Description Fred Bricon CLA 2010-10-14 18:05:22 EDT 
Build Identifier: 20100915173744

Seems like Bug #302644 stroke again. I'm developing m2eclipse-wtp and testing it with Eclipse 3.6.1 ( Eclipse Web Developer Tools Version: 3.2.2.v201008100100-7O7CFbKEMf84nUlEJyX7-SPQjhYZ)

I'm often facing an Eclipse freeze on startup. I sometimes pass the splashscreen, but then java.exe sucks 100%CPU forever. I'm attaching a few threaddumps taken under a minute.

This is really painful. Only solution is to delete the workspace metadata and reimport the projects. 

Igor Fedorenko (https://issues.sonatype.org/browse/MNGECLIPSE-2375) pointed me to #302644. 

If there's anything we can do on m2eclipse' side I'd be glad to hear it.

Regards,

Fred Bricon

Reproducible: Sometimes

Steps to Reproduce:
Can't reproduce it, but I can provide workspace metadata if needed.

Assigning to Jason for initial investigation.
Comment 3 Jason Sholl CLA 2010-10-15 09:58:52 EDT 
This is similar to bug 327801, for now these will be tracked separately though to ensure both scenarios are fixed.  The problem is in Worker-4 at this line:

org.eclipse.wst.common.componentcore.internal.resources.VirtualComponent.getRawReferences(VirtualComponent.java:401)

From that line up the calls to JDT should not occur.
Comment 4 Jason Sholl CLA 2010-10-15 10:01:21 EDT 
Actually, upon looking at bug 327801, these are identical.
