A thread dump from my hung Eclipse process none

Description Kyle K. CLA 2010-12-01 13:56:16 EST 
Build Identifier: 20100917-0705

I've been experiencing a lot of IDE freezes over the past week or so.  It doesn't appear to be tied to any particular function as it's occurred during the following operations:

1) Attempting to save a modified Java file using CTRL+s
2) Trying to create a new Template for XML documents via Preferences -> XML -> XML Files -> Editor -> Templates
3) Changing editor tabs
4) Hovering my mouse over a node in the Package Explorer

Reproducible: Sometimes

Steps to Reproduce:
I'm unable to reproduce this with any regularity.  I can just guarantee that I'll hang at least 2-3 times a day.

I have a thread dump just after a recent hang via jvisualvm that I'll attach to this issue.

Ayushman, please investigate if the deadlock comes from JDT/Core.
Thanks.

JDT/Core is surely not in picture here. Kyle, have you installed any plugins on top of vanilla eclipse?
Comment 4 Kyle K. CLA 2010-12-02 12:37:31 EST 
My apologies for picking the wrong product & components.  I wasn't sure where this should be placed.

I do have quite a few plugins installed (as noted below).  Would you mind helping me associate this ticket with the proper product and component?

Comment 5 Olivier Thomann CLA 2010-12-06 15:12:06 EST 
Ayushman, please move it to the appropriate component.
Comment 6 Ayushman Jain CLA 2010-12-07 03:24:54 EST 
In this particular case of the save action, it seems like the progress dialog may be the cause for the hang. Moving to JDT/UI for comment. 

Also, Kyle, it will be helpful if you could provide a heap dump from another scenario where you found Eclipse hung.
Comment 7 Dani Megert CLA 2010-12-07 03:32:23 EST 
The stack trace does indicate a blocked UI thread. Also, it's not related to the scenario listed in comment 0.

Can you please attach more stack dumps when it hangs again and then reopen the bug? Currently there's nothing we can do without more details (steps;dumps).
Comment 8 Thorsten Möller CLA 2011-01-06 11:25:46 EST 
I'm experiencing the same problem with Eclipse Helios EE Service Release 1. Sometimes it occurs every second or third save using CTRL+S, which is really annoying. For me, deactivating Java -> Editor -> Save Actions -> Additional actions helps.

Please file a separate bug report with stack traces that show us where the time is spent.
