package com.sun.tools.attach;

The exception thrown when an agent fails to initialize in the target Java virtual machine.

This exception is thrown by VirtualMachine.loadAgent, VirtualMachine.loadAgentLibrary, VirtualMachine.loadAgentPath methods if an agent, or agent library, cannot be initialized. When thrown by VirtualMachine.loadAgentLibrary, or VirtualMachine.loadAgentPath then the exception encapsulates the error returned by the agent's Agent_OnAttach function. This error code can be obtained by invoking the returnValue method.
