* @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).
*
