nsk/sajdi tests are failing due to unable to attach to core file.

Next tests are failing:
nsk/sajdi/SACoreAttachingConnector/attach/attach001
nsk/sajdi/SACoreAttachingConnector/attach/attach002
nsk/sajdi/jdb/options/connect/connect002
nsk/sajdi/jdb/options/connect/connect004

Failures are reproducing on some linux machines. See comment for further information.

Issue also reproducing if attach to core files dumped
while tests execution via jdb using sun.jvm.hotspot.jdi.SACoreAttachingConnector.
