Profiling Snapshot

Product Version: NetBeans IDE 7.4 (Build 201310111528)
Updates: NetBeans IDE is updated to version NetBeans 7.4 Patch 2
Java: 1.7.0_40; Java HotSpot(TM) 64-Bit Server VM 24.0-b56
Runtime: Java(TM) SE Runtime Environment 1.7.0_40-b43
System: Windows 7 version 6.1 running on amd64; Cp1252; de_DE (nb)

When I copy some text (both in NetBeans and in other programs), NetBeans freezes for around 20-30 seconds.

What I did:
1. Select some lines of text (also works with just 1 character)
2. copy that text
-> NetBeans freezes for around 20-30 seconds (no user input is possible)
3. NetBeans can be used again now

I attached a profiling snapshot (from when I copied the text until after NetBeans can be used again).

I checked your snapshot and unfortunately, you took snapshot when netbeans is only waiting for next action. Sending to evaluate to bootstrap team since NbClipboard is there.

NbClipboard is not really part of Module System. Is it yours, Jan?

The profiling snapshot really does not give any clue.

Reporter, is the problem reproducible for you? Can you please take a thread dump during the freeze, or even better a few thread dumps with several seconds in between those, and attach to this issue?

Please, reopen when the dumps are available. Thanks.

I'm not able to reproduce the problem, as it didn't happen again.
