Hi Folks

I am working with a third-party application for financial analysis.  I observe 
that the application tends to crash when visualizing and rotating a 3D image of 
a surface, unless the VM arg "-XInt" is provided.  I also observe that the 
package has dependencies on VisAD (we do not know what version of VisAD is 
used).

-XInt is a VM arg which tells the JVM never to use the HotSpot compiler to 
compile Java bytecode into machine code.

-XInt has obvious performance implications, since all Java bytecode is always 
interpreted.

Without wishing to imply that there are any deficiencies in VisAD itself, has 
anyone else reported a similar issue (perhaps with earlier versions)?

Much obliged, Robin.
