Bug#948553: - backport to buster ?

[Landry Breuil]

hello,

this bug is now fixed in sid, but could it be a candidate for a fix in 
stable/buster ? as of now, tomcat9 is a bit broken wrt systemd in 
stable, and i see two options to fix it:
- only backport the commit 
(https://svn.apache.org/viewvc?view=revision&revision=1853508) on top of 
catalina.sh to just fix the issue
- fix the systemd unit ?
- update to 9.0.17 in buster ?
