Hi,
it seems that debian is not using the init script provided by the activemq
project.
I downloaded and extracted the current debian script of the activemq package
from https://packages.debian.org/jessie/all/activemq/download
(see attached file)
In 2009 the init script of the activemq distribution was a really bit ugly.
I did a rewrite years ago but it was hard to get the new script in a maintained
state because the project was really slow in reviewing and accepting patches.
In the last weeks i did some further improvements and got some patches to
upstream.
It´s hard to write and maintain a general init script which can be used on
various unix/linux platforms.
I really welcome any feedback which helps me to really improve that script.

Regards
Marc
