Startup issues with Pentaho biserver ce 5.2.0

Hi,

I was trying to install and start the pentaho BA server 5.2.0 version in my linux box, it thows the following error in the logs.

====================

====================

Im getting the login window after the startup, but end up with a blank blue page after sucess login.

Can I get some advice on this.

Pentaho 5.0 is running smoothly on the same box.

Thank you,
