|
* 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
