Bug#831225: tomcat8: init.d script doesn't start catalina properly and cannot stop it afterwards

Package: tomcat8
Version: 8.0.14-1+deb8u2
Severity: normal
Dear Maintainer,
I downloaded and started docker image with tomcat8 preinstalled:
$ docker run -d -p 8080:8080 alkacon/opencms-docker:10.0.1
Loggin into the image and trying to stop the tomcat8 container fails and
logs:
# # Look for running instance id with 'docker ps'. E.g. 3186238ed456
$ docker exec -it 3186238ed456 /bin/bash
root at 3186238ed456:/# /etc/init.d/tomcat8 start
> Stopping Tomcat servlet engine: tomcat8 (not running).
Using the init daemon to restart the tomcat also fails:
root at 3186238ed456:/# /etc/init.d/tomcat8 stop
> Stopping Tomcat servlet engine: tomcat8 (not running).
Inspecting the /etc/init.d/tomcat8 script I have to admit that I'm really
confused. I have annotated the code, so you can follow:
case "$1" in
184 start)
184b # Sanity checks ...
....
194
195 log_daemon_msg "Starting $DESC" "$NAME"
196 if start-stop-daemon --test --start --pidfile "$CATALINA_PID" \
197 --user $TOMCAT8_USER --exec "$JAVA_HOME/bin/java" \
198 >/dev/null; then
198b # Acording to the man, start-stop-daemon --test always
198c # return 0
199
200
201 # Regenerate POLICY_CACHE file
....
208
209 # Remove / recreate JVM_TMP directory
....
216
216b # Starts tomcat
217 catalina_sh start $SECURITY
218 sleep 5
219 if start-stop-daemon --test --start --pidfile "$CATALINA_PID" \
220 --user $TOMCAT8_USER --exec "$JAVA_HOME/bin/java" \
221 >/dev/null; then
221b # Again, always 0. This "then" branch is always
221c # executed
222 if [ -f "$CATALINA_PID" ]; then
222b # XXX: why is the PID file deleted!?
223 rm -f "$CATALINA_PID"
224 fi
224b # XXX: This should be the success case and return 0?
225 log_end_msg 1
226 else
227 log_end_msg 0
228 fi
If I get it correctly, after the sleep, the script enters always the "then"
clause of the if, removes PID file and returns failure.
I have testet switching the "then" and "else" clauses, and it works as expected.
