| * @summary converted from VM Testbase nsk/jvmti/RedefineClasses/redefclass029. |
| * VM Testbase keywords: [quick, jpda, jvmti, noras, redefine] |
| * VM Testbase readme: |
| * DESCRIPTION |
| * The test exercises that the JVMTI function RedefineClasses() |
| * enable to redefine a static inner (nested) class properly. |
| * Redefiniton is performed in asynchronous manner from a separate |
| * thread when the VM is provoked to switch into compiled mode. |
| * The test works as follows. Two threads are started: java thread |
| * executing a nested class to be redefined, and native one executing |
| * an agent code. Then the nested class method 'redefclass029HotMethod()' |
| * is provoked to be compiled (optimized), and thus the JVMTI event |
| * 'CompiledMethodLoad' should be sent. After that, the agent redefines |
| * the nested class. Different kinds of outer fields are accessed from |
| * executing methods in both versions of the nested class. |
| * Upon the redefinition, the main test thread verifies via the outer |
| * fields values that the nested method 'run()' having an active stack |
| * frame stays obsolete but the other nested methods have been redefined. |
| * It also verifies that the outer class is still can access the nested |
| * class fields after the redefinition. |
