Bug#451494: libapache2-mod-jk: Could not init service for worker

[Steve Dobson]

Package: libapache2-mod-jk
Version: 1:1.2.25-1
Severity: grave
Tags: patch
Justification: renders package unusable


After upgrading my ajp13 worker no longer initialised and connection to
the Tomcat server did not occure.

While investigating the problem I striped the workers.properties file down
to the bear minimum:
   worker.list=pugwash
   worker.pugwash.type=ajp13
as per http://tomcat.apache.org/connectors-doc/reference/workers.html

JK log file (trace level) gave the following:

[trace] map_uri_to_worker::jk_uri_worker_map.c (542): enter
[debug] map_uri_to_worker::jk_uri_worker_map.c (597): Attempting to map URI '/manual/page/Meister' from 1 maps

But downgrading to 1.2.18-3etch1 everything worked again.
