| * @summary converted from VM Testbase nsk/jvmti/scenarios/hotswap/HS203/hs203t004. |
| * VM Testbase keywords: [jpda, jvmti, onload_only_caps, noras, redefine, feature_hotswap, monitoring] |
| * VM Testbase readme: |
| * Description :: |
| * The test would redefine a class during method compilation, pops currently executing frame. |
| * The Test starts a Thread (MyThread). On preparing of MyThread compiled_method_load event is enabled. |
| * While running the thread, it calls a method (doTask2() ) for number of times (1000). |
| * That would cause this method to be compiled, which causes a jvmti callback for compiled method load. |
| * (Hint : to force method compilation -XX:CompileThreshold=900 is used). |
| * The class which holds this method is redefined with ./newclass/MyThread.java, Once the redefine |
| * is completed the thread is suspended, pops current frame and resumed. |
| * The test is said to pass if the redefine is effective in compile_method callback. |
| * |
