* DESCRIPTION
|
|
* The test exercises JVMTI function GetStackTrace via breakpoint
|
|
* and consequent popping a frame.
|
|
* The test starts a new thread, does some nested calls, stops at breakpoint,
|
|
* pops frame, catches single step event and checks if the number of frames
|
|
* in the thread's stack is as expected and the function returns all
|
|
* the expected frames.
|
|
* COMMENTS
|
|
* Ported from JVMDI.
