This bug affects the following SA-JDI tests of testbase_vm:

    nsk/sajdi/jdb/options/connect/connect001
    nsk/sajdi/jdb/options/connect/connect002
    nsk/sajdi/jdb/options/connect/connect003
    nsk/sajdi/jdb/options/connect/connect004

These are new tests for SA-JDI connectors support in JDB,
which will appear in the next r29 release of testbase_vm
coming soon.
