See bug 366048 comment 25 ff. where we discuss how the stack is growing over time. To confirm this, if you ever see this again, you could: - keep Eclipse running for a while - periodically request stack dumps using jstack - check if the above stack grows at approx. 1 frame per 30 secs. *** This bug has been marked as a duplicate of bug 366048 ***
