0003986: Attach handler null pointer exception when stopping Resin 4.0.6

Notes
(0004527) mros2stf 04-12-10 11:51	I believe the issue is that watch-dog manager is not creating his log file watchdog-manager.log.

(0004534) mros2stf 04-14-10 12:44	Attach API I'm sure this has to do with watchdog-manager.log not being created. The Attach API is a Sun Microsystems extension that provides a mechanism to attach to a JavaTM virtual machine. A tool written in the Java Language, uses this API to attach to a target virtual machine and load its tool agent into that virtual machine. For example, a management console might have a management agent which it uses to obtain management information from instrumented objects in a virtual machine. If the management console is required to manage an application that is running in a virtual machine that does not include the management agent, then this API can be used to attach to the target virtual machine and load the agent.
