JDI spec: several pending JDI step requests are allowed per one thread

Name: egR10015 Date: 04/19/2001



HS1.3.1-rc2-b22 and HS1.4.0-beta-b60 fail to pass the following test

nsk/jdi/EventRequestManager/createStepRequest/crstepreq001

from testbase_nsk on all platforms. The test successfully
creates several StepRequest objects per one debuggee's thread,
but should not.

The JDI spec 1.3 on the method
com.sun.jdi.request.EventRequestManager.createStepRequest() says:
----------------------------------------------------------------------
"...
Only one pending step request is allowed per thread.
...
Throws:
DuplicateRequestException - if there is already a pending
         step request for the specified thread.
..."
----------------------------------------------------------------------

According to the spec the test checks that only one pending JDI step
request is allowed per thread, i.e. the JDI method createStepRequest()
properly throws a DuplicateRequestException if there is already
a pending step request for the specified thread.

To reproduce the bug run
sh doit.sh $JAVA_HOME [$JAVA_OPTIONS]
