Another OOME. It seems to be editor-related again, since memory consumption grew a lot as I was opening editor tabs. Around 25 editor tabs were open by the time the error occurred.

It seems so.

For now I'm implementing dropping of view hierarchy for inactive files.
A definitive solution for this problem will be lazy-children-views described in issue #183646.
Comment 6 Vitezslav Stejskal 2010-04-07 16:19:41 UTC 
The memory consumption should be much lower after:

Integrated into 'main-golden', will be available in build *201004090201* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Log: #183503: Composite AttributeSets should be smaller now: there is a special class for composites of size == 2, and "big" (size > 2) composites are now backed-up by an array instead of LinkedList.
Comment 9 Miloslav Metelka 2010-05-03 15:31:10 UTC 
Since issue #183646 was fixed this should no longer happen.
