Subject RE: Max possible ram usage

In addition, you also need to ensure that there is enough RAM left for the
OS to use when assigning native heap.

AFAIK the general rul of thumb is to have the same anount of RAM you assign
to the JAVA HEAP left to the OS for the native heap.

That is just java related. 
Tomcat has no upper limitations.

The maximal memory depends on the vm implementation.
You might try a newer version of the jdk or a jdk from a different vendor.
