(117/211) 3759 - jedit stopps when I type (windows 8)

Please follow these steps:

1.) install a JDK and start this program: "C:\Program Files\Java\jdk1.7.0_09\bin\jvisualvm.exe" (change the path accordingly)
2.) in VisualVM: attach to the running jEdit process by dobule clicking the process
3.) choose tab "Thread" and click the "thread dump" button
4.) attach the thread dump here.

Hi,

thanks for the report. This seems to be some kind of deadlock:

1.) AWT event queue thread is waiting on the WriteLock of the Buffer:

\"AWT-EventQueue-0\" prio=6 tid=0x045bdc00 nid=0x18ac waiting on condition
\[0x05b8e000\]

Your thread dump sadly doesn't reveal the owner of the lock "0x290197d8". This is the important thread, if this thread is block, the GUI will be blocked.

2.) The sidekick plugin is waiting for the mediatracker lock, but that seems to be unrelated.

You may try to disable the sidekick plugin and see if this solves your problem?

Chris responded:
"Your Analysis ist great. The deactivation of the SideKick-Plugin helps to work with the
Editor. Unforunately the plugin is necessary to work with the Lilypond Plugin. I used jEdit
mainly for work with Lilypond. The Workaround: deactivate SideKick (and Lilypond) - work
in the Editor - activate Lilypond and sidekick - compile the file - deactivate .... would work,
but ist not nice. The Moment I type something without deactivation, lilypond freezes.

Do you have any idea how to repair sidekick, get the media-traker to answer or use
lilypond without it?"

Hi Chris,

would you please provide the version numbers of the plugins you are using? You can find the version numbers in "Plugins->Plugin Manager".

Can you also please attach the test.ly file in this bug report?

I'll try to reproduce the bug.
