 * @summary converted from VM Testbase nsk/aod/VirtualMachine/VirtualMachine09.
 * VM Testbase keywords: [feature_282, jdk]
 * VM Testbase readme:
 * Description :
 *     Test checks work of Attach API (com.sun.tools.attach).
 *     Test is based on the nsk.share.aod framework.
 *     This test checks method VirtualMachine.loadAgentLibrary(String agent).
 *     Test checks following spec clause: "Agent_OnAttach function is invoked even if the agent library was loaded
 *     prior to invoking this method". In this test the same agent library first loaded via VM command line
 *     option 'agentlib:', then it is loaded using method 'System.loadLibrary' and than dynamically attached.
 *
