| * DESCRIPTION |
| * This JVMTI test is for HS201 scenario of "HotSwap" class file replacement |
| * area. |
| * The test exercises the RedefineClasses, IsMethodObsolete and PopFrame |
| * jvmti's functions when an user-defined exception is being thrown |
| * for a case when original and redefined methods are equivalent. |
| * Checked statements: |
| * - redefined method having active stack frames continues to run |
| * with original bytecodes, in this case IsMethodObsolete returns true |
| * - after popping a frame, the execution state is reset to the state |
| * immediately before the called method was invoked, when the thread is |
| * resumed |
| * The test does the following steps: |
| * 1) enables events ClassLoad, Breakpoint, Exception, ExceptionCatch; |
| * 2) starts new thread which invokes a method throwing a not-yet-loaded |
| * user-defined exception; |
| * 3) upon ClassLoad occurrence for the exception, sets a breakpoint |
| * in its constructor. |
| * 4) upon reaching the breakpoint, enables SingleStep. |
| * 5) redefines the exception within SingleStep callback, new bytecode |
| * contains the changed constructor; |
| * 6) checks that stepping is continued in the obsolete constructor; |
| * 7) suspends started thread and pops a currently executing frame; |
| * 8) after resuming checks that stepping is continued in the redefined |
| * constructor; |
| * 9) redefines the exception once more within triggered callbacks |
| * Exception, ExceptionCatch caused by throwing in the method. |
| * COMMENTS |
| * Test fixed according to test bug: |
| * 5068937 TEST_BUG: JVMTI HotSwap tests hs201t00* use wrong JNI environment |
| * Fixed 6281402: TEST_BUG: race condition in test nsk/jvmti/scenarios/hotswap/HS201/hs201t001 |
