Comment 6 for bug 191075

I have done some testing and as it seems the problem is definitely related to java IcedTea 64-bit.

I have done exactly the same steps as written in this comment/Bug report to perform a local build.
https://bugs.launchpad.net/ubuntu/+source/icedtea-java7/+bug/177514/comments/16

 # apt-get install icedtea-java7-jdk
 # apt-get build-dep icedtea-java7-plugin
 # apt-get -b source icedtea-java7-plugin icedtea-java7-bin icedtea-java7-jre icedtea-java7-jdk
 # dpkg -i icedtea-java7*.deb

The result is that ProjectX is running with no problems.
I have tested it by cutting a little video and no problems appeared to me.

best wishes
