Description mydevelopers 2014-04-19 15:40:04 UTC

Please see the logs/ heapdump at www.mydevelopersgames.com/RSC1397521428587.zip

We have been having this problem with our users for some time now. We cannot replicate the problem and not all users are having it however we have seen similar heapdumps before. We have tried to limit the number of highlights returned by the semantic analyzer plugin but the bug does not seemed to be resolved.

Please let us know how to fix this problem.

Thanks!

Which version of NetBeans platform do you use?

AquaTabbedPaneContrastUI#1 instance is holding 200MB with 7317 elements in htmlViews field. This looks similar to issue #230493. This memory leak can obscure problem with highlightitem instances. Since memory leak in AquaTabbedPaneContrastUI#1 is Mac OS X only issue, are you able to reproduce the problem with highlight item instances on Windows or Linux?
