Hi,

Sorry for my late reply.

I think being able to force rotation via jcmd seems like a good feature. 
Files are currently opened in append mode so it should already be 
possible to use external log rotation tools by copying and truncating 
the files. Still I think it would be nice to provide the jcmd for 
rotation as well.

I can see some small issues with the implementation, but we can deal 
with that during the review.

Thanks,
Marcus
