I don't think that true.  At least not on Windows.  Though on Windows there are different "classes" or priority,  The full range of Java priorities is mapped to a narrow range of the native thread priorities.  The highest we could go from the Java side still left room for higher native priorities.

There is.  We just had to do that in our product because we needed a specific thread to be TIME_CRITICAL thread priority on Windows and possibly have the process be in the REALTIME priority class.
