----------------------------------------

As SA-JDI is read-only implementation of JDI, several read-only
methods of VirtualMachine should throw VMCannotBeModifiedException.
However, the following read-only methods do not throw this exception:

    VirtualMachine.eventQueue()
    VirtualMachine.eventRequestManager()
    VirtualMachine.exit()

All other read-only methods of VirtualMachine interface throw
expected VMCannotBeModifiedException.

This failure is easily reproduced with any of SA-JDI connectors on Solaris
On Linux all tests are crashed because of blocking bug:
4975660 SA-JDI: SAPIDAttachingConnector.attach() causes debugger VM crash on Linux

To reproduce this failure:
  cd /net/jano.sfbay/export/disk20/GammaBase/Bugs/<this bug number>
  sh build.sh $JAVA_HOME
  sh run_eventqueue.sh [-pid | -core] [-g] [-v] $JAVA_HOME [JAVA_OPTS]
  sh run_reqmgr.sh [-pid | -core] [-g] [-v] $JAVA_HOME [JAVA_OPTS]
  sh run_exit.sh [-pid | -core] [-g] [-v] $JAVA_HOME [JAVA_OPTS]
where:
    -pid - run test with pid attaching connector (default)
    -core - run test with core attaching connector
    -g - run test with java_g binaries
    -v - run test in verbose mode

Here are typical tests output:

# ERROR: VirtualMachine.eventQueue() does NOT throw VMCannotBeModifiedException for
SA-JDI connector:
# ERROR: connector: sun.jvm.hotspot.jdi.SAPIDAttachingConnector
# ERROR: got eventQueue: sun.jvm.hotspot.jdi.EventQueueImpl@dc57db

# ERROR: VirtualMachine.eventRequestManager() does NOT throw
VMCannotBeModifiedException for SA-JDI connector:
# ERROR: connector: sun.jvm.hotspot.jdi.SAPIDAttachingConnector
# ERROR: got object: sun.jvm.hotspot.jdi.EventRequestManagerImpl@dc57db

# ERROR: VirtualMachine.exit() does NOT throw VMCannotBeModifiedException for SA-JDI
