> Reproducible: Always

What are the steps to always reproduce it?
Comment 3 Bill Wang CLA 2012-07-06 10:25:19 EDT 
en, it seems sometimes. not always.

when I working on eclipse, I am not sure why it happened.
I got a error dialog, and I close it, I can continue my work.

and I find this exception in the error log.
Comment 4 Holger Meyer CLA 2012-10-15 07:30:43 EDT 
The issue seems to appear sporadic. Assumption is that it happens while in the background any jobs are creating/deleting markers.

We use Eclipse 3.7.2 and Java 1.7.0_4.

Here is the stack trace:

Comment 8 Dani Megert CLA 2013-10-03 04:39:16 EDT 
MarkerCategory accesses markers.getMarkerEntryArray() which can change in a different thread, hence the sporadic AIOOBE.
