* @summary converted from VM Testbase nsk/jvmti/PopFrame/popframe009.
* VM Testbase keywords: [quick, jpda, jvmti, noras]
* VM Testbase readme:
* DESCRIPTION
* The test exercises JVMTI function PopFrame(thread).
* The test creates a child thread setting breakpoint to the method
* checkPoint, then starts the thread which does the following:
* - calls method checkPoint
* - recursively calls method fibonacci (intended to be inlined)
* - calls method checkPoint
* Starting the child thread the test waits for the first breakpoint in
* method checkPoint, then tries to catch the child thread being running
* method fibonacci and if succeeded do multiple PopFrame till method
* run. Finally the test waits for the second breakpoint in method
* checkPoint and verify the result of the method fibonacci call.
* COMMENTS
* This test is based on the following bug:
* 4647643 SEGV or SIGBUS in JVM with PopAsynchronousTest
* Ported from JVMDI.
