 * @summary converted from VM Testbase nsk/jvmti/AttachOnDemand/attach001.
 * VM Testbase keywords: [jpda, jvmti, noras, feature_282, vm6, jdk]
 * VM Testbase readme:
 * Description :
 *     Test tries to load java and jvmti agents 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 the terms of this framework
 *     java application running in the VM where agent is loaded to is called 'target application'.
 *     In this test target application tries to attach java and native agents to the same VM where target application
 *     is running. Test just checks that agents can connect and run (agents don't perform any specific
 *     checks).
 *
