#2379: Re3gistry fails due tomcat9 not supporting java8

Component:  OSGeoLive  |   Keywords:  re3gistry tomcat
-----------------------+------------------------------
 I’m updating the Re3gistry installer script. Re3gistry is a java8 software
 and requires deploying two apps into tomcat (re3gistry2 and
 re3gistry2API). I made some changes in the installer but arrived at the
 following error.

 After some research, I found out that tomcat9 looks like it does not have
 support for version 52 (java 8) in Ubuntu 22.04 LTS. If I’m not wrong,
 OSGeo Live is based on this version. A thread about this issue:

 [https://bugs.launchpad.net/ubuntu/+source/tomcat9/+bug/1972829]

 I’m not sure how to approach this issue, if it should imply changes in
 OSGeo Live base version or if we should try to install a different tomcat
 version in the re3gistry installer or try a workaround as it is explained
 in the last thread.

 Thanks for your help in advance.
