Re: [Wrapper-user] Restart request causes 5 rapid retries and death

Hubert,
    Thanks for pointing this out.  The behavior of replacing the 
remaining timeout with the
new one was historical.  In the first versions of the Wrapper, the 
internal timeouts were
not nearly so configurable and the application took much more control of 
the startup
and shutdown of the JVM.

    The way the Wrapper is now used however, this no longer makes any 
sense.  It is
only the way it still because I had not given it any thought.

    I have modified both the signalStarting and signalStopping methods 
so they will
now attempt to set a new timeout "millis" milliseconds in the future.  
If the existing
timeout is already longer then the new timeout will be ignored.  Ie, it 
will only have
any meaning if the result will be to extend the timeout.

    This is checked in to SVN and will be in the next release.

    Cheers,
    Leif
