 * @summary converted from VM Testbase nsk/jvmti/scenarios/hotswap/HS202/hs202t001.
 * VM Testbase keywords: [quick, jpda, jvmti, noras, redefine, feature_hotswap]
 * VM Testbase readme:
 * 1. Set breakpoints in several methods when Object.wait(),
 * Object.notify(), Object.notifyAll() are in use in these methods.
 * 2. Upon reaching a breakpoint, enable SingleStep.
 * 3. Redefine an java.lang.Object class within SingleStep callback
 * when one of its methods is called by the tested method.
 * 4. Pop a currently executed frame.
 * This case is not possible as we need to keep break points on wait, notify and notifyall which are native methods.
