Installing 6.3.1 on Ubuntu

I am new and trying to install 6.3.1 on Ubuntu. Some time back, I had 6.2 which was fine till a Java update made it stop.

I tried installing 6.3.1. The installation went fine but at the end, there was an error message. After that BonitaSoft wont launch.

Can anyone please assist?

Error Message:

There has been an error. Error running /my_space/BonitaBom6.3.1/jre/bin/java -Xmx512m -XX:MaxPermSize-512m -jar "/my_space/BonitaBom6.3.1/plugins/org.eclipse.equinox/launcher_1.3.0.v20130327-1440.jar" -product.org.bonitasoft.initializer -data @,y_space/BonitaBpm6.3.1/workspace" -noSplash: Child process exited abnormally. The application will edit now.

Once again, I am new to BonitaSoft. Any help would be greatly appreciated.

Thanks,
