I'm using KWin.

That folder doesn't exist, but I have folder 
~/.java/.userPrefs/edu/umd/cs/findbugs
The current user has all permissions and ownerships on all files and folders.

I tried, then I run findbugs and the folder was NOT created back.

Tried still with no luck.

Hmmm... What window manager are you using?  It's a bit suspicious that
the application works correctly as root but not as a normal user for you.

You might want to check the ownership of the files beneath:

  ~/.java/.userPreferences/edu/umd/cs/findbugs/


findbugs is going to want to write a prefs.xml file beneath that tree.
If the permissions and ownership all look reasonable, you might try
deleting the entire tree with:

  rm -rf ~/.java/.userPreferences/edu/umd/cs/findbugs

I tried going back and forth between 1.7 an 1.8 and wasn't able to cause
it to fail, so I don't think that's related.  Note however that the
wrapper script resolves "java" via /etc/alternatives/java, which points
directly to "/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java" on my
system, so changing "/usr/lib/jvm/default-java" may not have had the
desired effect.

You can use "sudo update-alternatives --config java" to set this up
system-wide.

Thank you,
tony

No, it doesn't work.

I also tried to change the "/usr/lib/jvm/default-java" link to 
"java-1.8.0-openjdk-amd64" with no luck.

Hi Luca,

Thank you for the bug report.  I am not able to reproduce this bug
locally, but I believe it might be related to other reports of issues
with hangs related to GUI-based applications that use threads, for example:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=797595
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=814901
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=802701

Specifically, if you could try the fix suggested in the following and
report your findings, that would be helpful.

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=802701#25

I am also modifying the severity of the bug to important from grave.
findbugs is used in contexts other than just the GUI mode (for example,
on the command-line as part of a build chain), and does work in that
context and also as a GUI for others.

Thank you,
tony

Package: findbugs
Version: 3.0.1-2
Severity: grave
Justification: renders package unusable

Dear Maintainer,
I installed the findbugs package and I launched it by the following command:

$ findbugs

The window of the GUI opened, so I clicked the "File" menu and the application
froze.

The console printed out:

(java:6177): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0'
failed

(java:6177): Gdk-CRITICAL **: gdk_screen_is_composited: assertion
'GDK_IS_SCREEN (screen)' failed

I had to close the running process, which was the following one (under "ps
-fe"):

java -classpath
/usr/share/findbugs/lib/findbugs.jar:/usr/share/java/dom4j.jar:/usr/share/java/junit4.jar:/usr/share/java
/commons-
lang.jar:/usr/share/java/jaxen.jar:/usr/share/java/jdepend.jar:/usr/share/java/asm4.jar:/usr/share/java/asm4-commons.jar:/usr/share/java/asm4-tree.jar:/usr/share/java/ant.jar:/usr/share/java/jcip.jar:/usr/share/java/jsr305.jar:/usr/share/java/jFormatString.jar:/usr/share/java/bcel.jar
-Dfindbugs.home=/usr/share/findbugs -Xmx768m
-Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel
edu.umd.cs.findbugs.LaunchAppropriateUI

The application appears to work when:

1) launching the following command:
$ java -jar /usr/share/java/findbugs.jar

2) running it under root permissions, e.g.:
# findbugs
