I am sorry but I am marking this as wontfix. The snapshots shows that there was 17s spent in less than 1000 invocations of java.lang.Object.notify(). I think this might be some Solaris oddity. It would need a Solaris expert to further explain how is this possible. I don't think this one reports is worth a lengthy examination. Closing. If you disagree please read the snapshot and suggest what could be done for this not to happen.
David. I just got the issue on Linux. Freeze is for 50 sec. Mila, please, have a look, what's going on.

IMHO this is related to issue #90901. If there are many DocumentLine objects for the source then performance can become poor.
Please update Target Milestone.
