Two threads are started. One is a java * thread creating and executing a local class in an instance * invoker method of the outer class. Second is a native thread * executing an agent code. Then the local class method * 'redefclass030HotMethod()' is provoked to be compiled (optimized), * and thus the JVMTI event 'CompiledMethodLoad' should be sent. After * that, the agent redefines the local class. * Different kinds of outer fields and a local variable of the outer * invoker method are accessed from executing methods in both versions * of the local class. Upon the redefinition, the main test thread verifies * via the outer fields/local variable values that the inner methods * have been redefined. It also verifies that the outer class * is still can access the local class fields after the redefinition. * COMMENTS * * @library /vmTestbase * /test/lib * @run driver jdk.test.lib.FileInstaller . . * @build nsk.jvmti.RedefineClasses.redefclass030 * * @comment compile newclassXX to bin/newclassXX * @run driver nsk.share.ExtraClassesBuilder * newclass * * @run main/othervm/native * -agentlib:redefclass030=-waittime=5 * nsk.jvmti.RedefineClasses.redefclass030 * 1000 ./bin */
