 * @summary converted from VM Testbase nsk/jvmti/AttachOnDemand/attach045.
 * VM Testbase keywords: [jpda, jvmti, noras, feature_282, vm6, jdk]
 * VM Testbase readme:
 * Description :
 *     Test tries to load 4 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'.
 *     This is stress test, 4 jvmti agents are loaded to the VM. Agents execute following actions:
 *         - agent045Agent00: enables ClassLoad event and from event handler calls GetClassSignature
 *         for loaded class
 *         - agent045Agent01: enables ClassPrepare event and from event handler calls GetClassSignature
 *         for loaded class and also class GetLoadedClasses
 *         - agent045Agent02: enables ThreadStart and ThreadEnd events, from event handlers calls GetThreadInfo
 *         for started or ended thread, and also calls GetAllThreads
 *         - agent045Agent03: enables ThreadStart and ThreadEnd events, from event handlers calls GetThreadInfo
 *         for started or ended thread, and also calls GetAllThreads
 *         - agent045Agent04: enables VMObjectAlloc event, from event handler calls GetThreadInfo for thread
 *         allocating object and calls GetClassSignature for allocated object class. Also after after each 10th event
 *         agent calls ForceGarbageCollection
 *     When each agent receives expected number of events agent finishes work (all events received by agents are
 *     provoked by the target application).
