* @summary converted from VM Testbase nsk/aod/VirtualMachine/VirtualMachine07.
* 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 methods VirtualMachine.loadAgentLibrary(String agent) and
* VirtualMachine.loadAgentLibrary(String agent, String options).
* Test checks following cases:
* - it is possible to pass options to agent using loadAgentLibrary(String agent, String options)
* - it is possible to specify null options (in this case zero-length is passed to the Agent_OnAttach)
* - if Agent_OnAttach returns error code loadAgentLibrary throws AgentInitializationException and
* AgentInitializationException.returnValue() returns this error code
*
* @library /vmTestbase /test/hotspot/jtreg/vmTestbase
