Graceful Shutdown

JVM has a shutdownHook Runtime.getRuntime.addShutdownHook(Thread) which allows us to register a shutdown hook. However, it doesn't work well with Windows. It responds to CTRL-C, but doesn't react when the process is killed (from task manager, or service console). In Linux/Unix it does work.

So an alternate is to add stop handling in JavaService, which run java class as NT service, and provides an adaptor layer .

licAgentService.exe -install "HiPath Wireless License Agent" %EMS_JAVA_HOME%\bin\client\jvm.dll 
-Xms16m -Xmx64m 
-Djava.class.path=bootstrap.jar;%EXTRA_CLASSPATH% 
-Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8100,suspend=n
-Djava.library.path=%EMS_HOME%\lib 
-start com.siemens.bk.lic.bootstrap.Main 
-stop com.siemens.bk.lic.bootstrap.Main -method systemExit
-out .\logs\stdout.log 
-err .\logs\stderr.log 
-current %LICAGENT_HOME% 
-depends "License Agent","HiPath Wireless RMI" 
-auto 

With the debug option, we can debug a service too.
In Windows Registry \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\, we can review all the option settings of the service.
