Problem in sun java

[Rajeev Sharma]

I am using sun java 6 on my ubuntu 8.04. I was trying to execute a jar file from the command line and I get a crash in command java. I was using ubuntu 7.10 earlier and java was working fine.

here is "java -version" command output:

rajeev@rajeev-dell:~$ java -version
java version "1.6.0_04"
Java(TM) SE Runtime Environment (build 1.6.0_04-b12)
Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing)

here is the command line output when I try to execute a jar file:

rajeev@rajeev-dell:~$ java -jar /usr/share/doc/sun-java6-demo/demo/jfc/SwingSet2/SwingSet2.jar

Changed the affected package to sun-java6

Does prefixing your command with LIBXCB_ALLOW_SLOPPY_LOCK=1 fix the problem?
i.e. try running

LIBXCB_ALLOW_SLOPPY_LOCK=1 java -jar /usr/share/doc/sun-java6-demo/demo/jfc/SwingSet2/SwingSet2.jar

Hi Atreju,

If I give the command 'LIBXCB_ALLOW_SLOPPY_LOCK=1 java
-jar /usr/share/doc/sun-java6-demo/demo/jfc/SwingSet2/SwingSet2.jar' it
works fine.

Now I am able to execute the jar file correctly.
