If you close all your open editors and then restart do you get the same? Do you have Build Automatically enabled? I'd recommend disabling it before exiting Eclipse.

[erkinalp]

Did what you told and groovy-related errors disappeared. Eclipse core plugins still are throwing exceptions.

[eric-milles]

What I am seeing in the stack traces is that there is contention for a lock as bundles are started and editors are opened and builders are run.

[erkinalp]

What should I do?

[eric-milles]

When you start eclipse now, what errors are seen?
