JabRef is using threads, so the same reasoning applies: unless
XInitThreads is called by awt, it will not be thread-safe, and thus any
kind of funky thing may happen.

There is a problem with JabRef that could be the same root cause.  There
is a discussion including stack traces (wherein the AWT-EventQueue-1
thread looks suspicious) available here:

Bug#802701: freemind: Freemind doesn't start with OpenJDK-8

[Samuel Thibault]

Hello,

Please have a look at
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=797595

Commenting the line in /etc/java-8-openjdk/accessibility.properties may
help with X11 issues, but I believe the ground issue is that the openjdk
awt toolkit doesn't tell X11 that it is using threads, and thus all
kinds of race conditions can happen within libxcb etc. just because
freemind happens to be using threads.

Thank you Samuel,

that did solve my problem.
After commenting out the line in the file accessibility.properties as you
described, freemind starts without any problems.

Bug#802701: freemind: Freemind doesn't start with OpenJDK-8

[Vincent Smeets]

Hallo,

further investigation shows that it's probably not a problem of freemind,
but of OpenJDK or X11 or something else.

OpenJDK-7 gives sometimes problems too. Sometimes I also see an error
message like:
Xlib:  extension "XInputExtension" missing on display ":0".
although the command xdpyinfo shows that the extension XInputExtension is
available in :0.

I have attached a stack trace of the time where all the threads are waiting
for something and the application hangs.

I don't think that this is a freemind problem. You can close this bug and I
will further investigate the problem and open a new one for the correct
package

Thanks,
Vincent

Hi Vincent,

Thank you for looking into it again.  We can leave the bug open and then
reassign it once we determine the root cause.  It may help others who
are encountering the same issue.

Cheers,
tony

Hi Vincent,

I'm also running testing + OpenJDK-8 and am not seeing any problem with
startup.  Can you try starting freemind with some additional debugging
and sharing the output?  For example:

Bug#802701: freemind: Freemind doesn't start with OpenJDK-8

[Vincent Smeets]

Package: freemind
Version: 0.9.0+dfsg2-1
Severity: normal

Hallo,

I have installed OpenJDK-7 and OpenJDK-8.
Freemind is starting normally with OpenJDK-7 but hangs in the splash
screen when started with OpenJDK-8.

When I start freemind without any settings
  $ freemind
it will use OpenJDK-8 (from java-wrapper) and doesn't start completely.
The spalsh screen will appear as an gray rectangle but with no image in
it. The application will hang at that point. A ^C or kill -TERM doesn't
work I can only recover by a kill -KILL to the JVM.
The command:
  $ JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 freemind
gives the same behaviour.

In contrast to that, the command:
  $ JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64 freemind
works normally and starts the application in a normal way.

Regards,
Vincent
