messagelog

I got another 8.0.2 crash.
Attached is the message.log

I was formatting a tiny XML doc (about 130 chars) at the time and there is a Window "Lengthy operation in progress" -> Formatting text, please wait...

Using VisualVM it is using about 17 %, and the heap is going up and down

It may be related to the other two crashes I have experienced :

Comment 2 Petr Pisl 2015-04-01 07:56:30 UTC

Do you think that is it possible to attach the xml file to reproduce the issue? Thanks

Comment 3 rjdkolb 2015-04-01 08:03:01 UTC

I can't reproduce the issue with the same XML :(

Comment 4 Petr Pisl 2015-04-01 08:07:10 UTC

It can be some time issue. If you find a way how to reproduce it or a test case it would be great.

Comment 5 rjdkolb 2015-04-01 08:09:18 UTC

I have an application snapshot if that helps ?

Comment 6 Svata Dedic 2015-05-15 09:44:24 UTC

Applicaton snapshot - do you mean profiler snapshot of the locked up application ?

Comment 7 rjdkolb 2015-05-15 10:01:39 UTC

Correct. From VisualVM.
I think I deleted it by mistake, sorry.
This issue has not come up again, 
but I will keep a look out.

Will a VisualVM Application snapshot help in future ?

Comment 8 Svata Dedic 2015-05-15 10:14:03 UTC

Sure: if you look at the attached threaddump, the AWT thread is waiting - but the waited-on thread manipulating the Document is in RUNNABLE state, so it must be doing something very long, large, slow.

Run the CPU profiler for a few minutes time while the IDE seems to be locked up, so the profiler collects enough data. If you can take also the heapdump, I could get to the exact data being processed.

Closing temporarilu until further input is available - thanks for your help !

Comment 9 rjdkolb 2015-05-15 10:19:42 UTC

Thanks Svata.

The XML was less than 2k big.
I'll keep a look out.

NetBeans crashes when editing XML files.

I can confirm the bug also.
NetBeans IDE 8.2 (Build 201705191307)

Whenever I try to edit XML or FXML files, I get this Retreive XML on the bottom, and the whole IDE freezes. 

Can only be closed if I kill the process.
