I have the same thing. Here’s my stack trace:

… 22 moreI’m running the full stack MyEclipse 6.0, with M2 (Maven) and Subversive plugins installed. I’m going to try and install 6.0.1 and hope this goes away, but in the meantime, is there any more info that would help fix this now that I have my workspace in a state where it’s happening like crazy meaning I can reproduce it easily?
livewire114,
Is there a certain set of behaviors that reproduce it every time for you from a cold start? I might be able to use that to reproduce it here…I faced the same problems in the last days. My feeling is similar, this only happens while running several tasks at the same time, and it seems to be related to the “progress” view which did not show running and waiting tasks properly. Today I imported a general eclipse configuration which is used on our project by many others, and this seems to fix the problem. I exported my configuration before, unfortunately I was not able to compare both configuration files.
If it is of interest, I can send those configuration files, if so please send a pm.
