[Wrapper-user] Windows 3.2.0 wrapper stops but jvm does not

G'day, mates. I'm having an odd problem in one of three programs that use the wrapper. I'd appreciate your advice & insight. We're using version 3.2.0 of the wrapper on Windows with the wrapper.dll library. The wrapper is installed as a Windows service. During an upgrade, our InstallAnywhere 2008 program calls its routine to stop this service and sometimes the service only takes 1 sec to shutdown instead of 6 sec. Using the wrapper debug log, I've determined that in this condition the wrapperp sends "send a packet SERVICE_CONTROL_CODE : 1" and then declares that "SmartPass stopped". Normally there's a long set of other activity. In this condition, the wrapper process stops but the child Java process does not. In fact, the Java process is totally unaware of the stop request and continues running. This causes installation problems. The service uptime required to see this ranges from 2 hours to 24 hours, so it's quite sporadic. I suspect either one of the disabled timeout parameters below or some wrapper bug is causing this problem. However, the same settings are in all of our programs and only this one is exhibiting a problem. wrapper.ping.timeout=0 wrapper.shutdown.timeout=0 I've also noted that this program is using the Java 1.6.0_02 client VM instead of the server VM and that we have not specified -Djava.awt.headless=true I reviewed the release notes for newer versions but didn't see any items that matched my case. Any help would be appreciated. Thanks! // failing, non-stopping case DEBUG | wrapperp | 2009/07/21 08:55:52 | send a packet PING : ping INFO | jvm 1 | 2009/07/21 08:55:52 | Received a packet PING : ping INFO | jvm 1 | 2009/07/21 08:55:52 | Send a packet PING : ok INFO | jvm 1 | 2009/07/21 08:55:52 | Non-daemon thread count = 18 - 1(system) = 17 DEBUG | wrapperp | 2009/07/21 08:55:52 | read a packet PING : ok DEBUG | wrapper | 2009/07/21 08:55:52 | Got ping response from JVM STATUS | wrapper | 2009/07/21 08:55:56 | Service is running.
