28  * VM Testbase keywords: [quick, jpda, jvmti, noras]
29  * VM Testbase readme:
30  * DESCRIPTION
31  *     The test checks that JVMTI function GetFrameCount returns proper
32  *     error codes when is called:
33  *       - with NULL passed as the second actual parameter,
34  *       - for a thread which is not is not alive.
35  * COMMENTS
36  *     Ported from JVMDI.
37  *     Updating test to meet JVMTI spec 0.2.30:
38  *     - check not alive thread
39  *     - check JVMTI_ERROR_THREAD_NOT_ALIVE instead of JVMTI_ERROR_THREAD_NOT_SUSPENDED
40  *
41  * @library /test/lib
42  * @run main/othervm/native -agentlib:framecnt02 framecnt02
