 * @test
 *
 * @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.
