I'd like to pass some java GC options when starting a tomcat6 service
on a windows server, eg. -Xloggc -XX:+UnlockExperimentalVMOptions -XX:
+UseG1GC

Tomcat (or the jvm) seems to disregard my options, or has trouble with
them, like "-XX:+PrintGCTimeStamps" would fail with "unknown option
+PrintGCTimeStamps".  The GC-log is never created.

I'm entering these options in the gui:

tomcat6w  //ES//tomcat6


I know my options are correct, when I start a TestGCThread with them,
they have the desired effect.

Any idea what I could be doing wrong?

Thanks,

Gerard
