Test Base : testbase_nsk

Platform (s) : solsparc
OS : 5.8
JDK : 1.4.0-FCS, 1.4.1-b17
------------------------------------------------------------------------------

The bug is reproduced since Merlin-FCS when debugee is executed on java_g.
The test provokes the JDI method com.sun.jdi.VirtualMachine.redefineClasses()
to throw the UnsupportedOperationException, trying to add method modifiers
when canUnrestrictedlyRedefineClasses() method returns false.
The test checks two different cases for suspended debugee and not
suspended one.

The test consists of the following files:
        redefineclasses008.java - debugger
        redefineclasses008a.java - initial debugee
        newclassXX/redefineclasses008a.java - redefining debugees
and will be available in release r16 of the testbase_nsk.

Steps to reproduce
=================
1. cd /net/sqesvr.sfbay/export/vsn/GammaBase/Bugs/<BugID>
2. sh doit.sh $JAVA_HOME
