A module in the target VM.
 Any method on ModuleReference which directly or indirectly takes ModuleReference as a parameter may throw VMDisconnectedException if the target VM is disconnected and the VMDisconnectEvent has been or is available to be read from the EventQueue. 
 Any method on ModuleReference which directly or indirectly takes ModuleReference as a parameter may throw VMOutOfMemoryException if the target VM has run out of memory. 
 Any method on ModuleReference or which directly or indirectly takes ModuleReference as a parameter may throw InvalidModuleException if the mirrored module has been unloaded. Not all target virtual machines support this class. Use VirtualMachine.canGetModuleInfo() to determine if the class is supported.
