 * VM Testbase keywords: [jpda, jvmti, noras, feature_282, vm6, jdk]
 * VM Testbase readme:
 * Description :
 *     Test tries to load java agents to the VM after the VM has started using
 *     Attach API (com.sun.tools.attach).
 *     This is negative test, it checks that attempt to attach java agent fails if
 *     main agent class has no proper 'agentmain' method.
