* DESCRIPTION
|
|
* The test exercises JVMTI event callback function FramePop.
|
|
* The test do some nesting/recursive calls watching frame pop
|
|
* events to be uniquely identified by thread/class/method/frame_depth.
|
|
* COMMENTS
|
|
* The test was created as a result of investigating the following bugs
|
|
* intended to write a regression test:
|
|
* 4335224 Bug 4245697 not completely fixed jevent.u.frame.frame incorrect
|
|
* 4504077 java: dbx should not hold on to a frameid after thread suspension

* Ported from JVMDI.
