Description
Almost every JVMTI agent or JVMTI test needs a fatal error handler that
prints out a symbolic name of the unexpected error.  This might seem to
be a convenience method except that error code may change with new 
versions of JVMTI, an agent may have been written to an older version 
of the spec and thus not have a new error code.
