 * DESCRIPTION

 *     This test performs checking for

 *         command set: StackFrame

 *         command: PopFrames

 *     Test checks that debugee accept the command packet and

 *     replies with correct reply packet. Also test checks that

 *     after current frame is popped the tested method is invoked

 *     second time.

 *     Test consists of two compoments:

 *         debugger: popframes001

 *         debuggee: popframes001a

 *     First, debugger uses nsk.share support classes to launch debuggee

 *     and obtain Transport object, that represents JDWP transport channel.

 *     Next, debugger waits for tested class loaded, requests methodID

 *     for tested method, sets breakpoint and wait for breakpoint reached.

 *     After breakpoint event is received with a thread, debugger gets top

 *     stack frame for this thread.

 *     Then, debugger creates command packet for StackFrame.PopFrames

 *     command with the found threadID and frameID, writes this packet

 *     to the transport channel, and waits for a reply packet.

 *     When reply packet is received, debugger parses the packet structure

 *     and checks if no reply data returned in the packet.

 *     Then, checks if the tested method will be invoked second time.

 *     To do so, it resumes debuggee and waits for BREAKPOINT event

 *     will be received again. If expected BREAKPOINT event is not received,

 *     debugger complains an error.

 *     Finally, debugger disconnects debuggee, waits for it exits

 *     and exits too with the proper exit code.
