 * @summary converted from VM Testbase nsk/jvmti/AttachOnDemand/attach024.
 * VM Testbase keywords: [quick, 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.
 *     Test checks that agent's JAR file is appended at the end of the system class path.
 *     Agent's JAR file contains modified class java.util.TooManyListenersException (it is assumed
 *     that this class isn't loaded before agent is loaded), agent instantiates TooManyListenersException
 *     and checks that non-modified version of this class was loaded from rt.jar (not from agent's JAR).
