30  * DESCRIPTION
31  *     The test exercises JVMTI function GetStackTrace for the current thread.
32  *     The test checks the following:
33  *       - if function returns the expected frame of a Java method
34  *       - if function returns the expected frame of a JNI method
35  *       - if function returns the expected number of expected_frames.
36  *     Test verifies stack trace for platform and virtual threads.
37  *     Test doesn't check stacktrace of JDK implementation, only checks 1st JDK frame.
38  * COMMENTS
39  *     Ported from JVMDI.
