Roman,

 From the message, I would say that the javac in javac.jar is trying to 
access the platform classes, and not recognizing that they are now in 
the platform image instead of rt.jar.

You need to either change your copy of javac, or else make it so that 
when you run javac from SPECjvm2008, you specify a -bootclasspath 
pointing to a suitable copy of rt.jar.
