 * @summary converted from VM Testbase nsk/jvmti/AttachOnDemand/attach030.
 * VM Testbase keywords: [jpda, jvmti, noras, feature_282, vm6, jdk]
 * VM Testbase readme:
 * Description :
 *     Test tries to load java agent to the VM after the VM has started using
 *     Attach API (com.sun.tools.attach).
 *     Test is based on the nsk.share.aod framework. In this framework each java
 *     agent starts new thread from the 'agentmain' method, and all test checks are executed
 *     in this thread. Also in the terms of this framework java application running in the
 *     VM where agent is loaded to is called 'target application'.
 *     Test checks that java agent can redefine classes using java.lang.Instrumentation (agent's JAR
 *     has attribute 'Can-Redefine-Classes: true'). Agent tries to redefine class loaded by the target
 *     application, also agent itself tries to load class and redefine it.
