Description sapanparikh18 2008-05-23 22:46:26 UTC

It seems that there are many things which NetBeans handles and there are many feature that it provides. But are they the
reasons of its tremendous slowness? My IDE hangs in trivial operations like formatting the code by right clicking and
clicking on "format" context menu. It also freezes when I press control button and click on a method name in some JSP. I
atleast have to kill my IDE 3 times a day. I am using a project with thousands of files but number of files never should
be a bottleneck, should it? I also believe that a message on the lower right corner saying "Indexing
c:\dir\project\name\"  is one of the big reason of the slowness.

A picture of task manager and netbeans. Look at the memory netbeans uses and also the CPU

Comment 2 Lukas Hasik 2008-05-26 07:08:39 UTC

screenshot of task manager doesn't help to track down the problem. Could you please take thread dump when the IDE freeze
or seems to be slow down? Follow http://wiki.netbeans.org/wiki/view/GenerateThreadDump
The JSP problem might be similar to issue 132662.

thank you for report

Comment 3 sapanparikh18 2008-05-27 14:59:07 UTC

Well following are the thread dumps after I right clicked on the JSP editor and clicked on "format". My IDE got locked
after that.

Comment 5 Lukas Hasik 2008-05-30 10:46:46 UTC

passing to web project. It seems that it happens with web projects and jsf.
CC'ing Tor as the first thread dump starts in gsf.

Comment 6 Marek Fukala 2008-05-30 12:33:38 UTC

I do not see any web code in the stacktraces except the last one which is apparently another issue (already repored I
belive). Looks like one holds the java parser lock but I do not see who. BTW it looks like the beginning of each
threaddump is missing. Reporter, can you try to *attach* (do not put to the textarea please) a full stacktrace?

Comment 7 sapanparikh18 2008-05-30 16:45:17 UTC

Well i am trying it through the command prompt(Pressing ctrl + break) and thus it just shows a limited number of lines.
Is there a way to pipe this out put directly in a file from command prompt?

Comment 8 Lukas Hasik 2008-05-30 20:08:55 UTC

change buffer size of the command prompt in properties accessible from "file" menu on the command prompt window

Comment 9 Marek Fukala 2008-06-02 08:56:28 UTC

just attach the netbeans log file. You can find it in 

${netbeans_home}/dev/var/log/messages.log

Comment 10 Marek Fukala 2008-06-02 08:59:01 UTC

Ooops, looks like the threaddump do not go to the log file, sorry.

Comment 11 sapanparikh18 2008-06-03 03:02:49 UTC

With kind of working I am doing now a days I am not able to reproduce the Issue. I will post the thread dump as soon as
it happens again.. Most probably this week.

Comment 12 sapanparikh18 2008-06-06 21:21:40 UTC

Attaching the whole thread dump as a text file

Comment 14 sapanparikh18 2008-06-06 21:26:07 UTC

I would also want to add that once running NB.exe from command prompt it crashed and showed the following message.
Am not sure if that's a  JVM issue or NB issue but i think it might be of any help.
Thanks a lot

Comment 15 Torbjorn Norbye 2008-06-06 22:15:53 UTC

This looks like a deadlock between the Java debugger and the Java editor (go to declaration code). Not sure who's at
fault... adding some debugger and Java support engineers to the CC to take a look.

Comment 17 sapanparikh18 2008-06-09 21:30:02 UTC

Attached hs_err_pid3152.log
Just took some time to find it.

Comment 18 Marek Fukala 2008-06-18 09:39:28 UTC

As Tor wrote, the goto declaration action tries to open a file, the file gets loaded by CloneableEditorSupport. During
the initialization in a RequestProcessor thread (EDT blocked, waiting for the code)
org.netbeans.modules.debugger.jpda.projects.EditorContextImpl.getMethodLineNumbers() calls
JavaSource.runUserActionTask() which then waits for the javac lock.

Who locks the javac is not clear to me. This issue doesn't seem to be web related, I am reassigning to java since.
Please look at it and possibly reassign. Thanks.

Comment 19 sapanparikh18 2008-06-18 19:33:33 UTC

I might be wrong but i feel that it only happens when the code is getting compiled. For example the last image attached
the compiling keeps going on even if I close the project entirely.

Comment 22 Jan Lahoda 2008-06-20 14:04:09 UTC

Seems to be caused by the change of threading during opening editors. Should be fixed:

Yes, we can include it in patch3
Reporter can you verify the fix in current dev build, please?

Please note that NetBeans 6.1 Patch3 cut-off is going to happen on close of
business August 5th. If you would like to have bugfix for this issue as part of
NetBeans 6.1 Patch3, then this issue must have information about bugfix' trunk
