>          Issue Type: Bug
>          Components: Procrun
>    Affects Versions: 1.0.10
>         Environment: Windows 7 SP1, Windows XP SP3
>            Reporter: Konstantin Kolinko
>            Priority: Minor
>             Fix For: 1.0.11

> The issue was reported on users<at>tomcat.a.o. I've confirmed that it is reproducible.
> The thread:
> http://tomcat.markmail.org/thread/r74penaeymdmeeic
> http://marc.info/?t=133839294900003&r=1&w=2
> To reproduce:
> 1. Install Tomcat 7.0.27. It contains Commons Daemon procrun 1.0.10.0.
> I tested with 32-bit versions on Windows 7 and Windows XP.
> 2. Start the service and service monitor application. The latter has to be run as administrator
under Windows 7.
> 3. Right-click tray icon and select "Thread Dump" from popup menu.
> 4. A message box appears:
> ---------------------------
> Application System Error
> ---------------------------
> Не удается найти указанный файл.
> Unable to open the Event Mutex
> ---------------------------
> ОК   
> ---------------------------
> The first line of the message comes from OS and means "The system can not find the file
specified."
> Enabling debug logging does not provide any additional information. The issue is reproducible
under Windows XP, so UAC is not involved.
> According to the original reporter a workaround is use the "jstack" utility that comes
with JDK. Other recipes can be found in [Tomcat FAQ|http://wiki.apache.org/tomcat/HowTo#How_do_I_obtain_a_thread_dump_of_my_running_webapp_.3F]
