* @test
*
* @summary converted from VM Testbase nsk/jdi/VirtualMachine/redefineClasses/redefineclasses002.
* VM Testbase keywords: [quick, jpda, jdi, redefine]
* VM Testbase readme:
* DESCRIPTION:
* The test against the method com.sun.jdi.VirtualMachine.redefineClasses()
* and checks up the following assertion:
* The redefined methods will be used on new invokes.
* If resetting these frames is desired, use
* ThreadReference.popFrames(StackFrame) with Method.isObsolete().
* The test consists of the following files:
* redefineclasses002.java - debugger
* redefineclasses002a.java - initial debuggee
* newclass/redefineclasses002a.java - redefining debuggee
* This test performs the following steps:
* 1. Setting breakpoint at line of method, which will be redefined.
* This method has a local variable <testedVar> and the breakpoint
* is placed after it's initializing.
* 2. When breakpoint event is arrived, Debugger requests initial
* value of <testedVar>
* 3. While VM suspended Debugger redefines the tested method.
* It is added new line, after execution point. That line changes
* value of <testedVar>, different from initial-value.
* 4. While debugee remains suspending, debuger tries to get value of
* <testedVar>. In this case AbsentInformationException is expected.
* 5. Popping the active frame and trying to get value again.
* It is expected, method will be not found in active stack frames.
* 6. Setting breakpoint at line after the new one and resuming debugee.
* 7. Trying to get new value of <testedVar>. It is expected the last
* value will be different from initial-value.
* The test should be compiled with "-g" option, so cfg-file redefines
* JAVA_OPTS variable.
* COMMENTS:
* Test was fixed according to test bug:
* 4778296 TEST_BUG: debuggee VM intemittently hangs after resuming
* - handling VMStartEvent was removed from the debugger part of the test
*
