Tomcat 9 not starting on linux - Catalina.sh can't use JAVA_OPTS

We have a new Tomcat 9 installed but we're having an issue when starting it.

It seems catalina.sh isn't able to work with the JAVA_OPTS, here what the log says :

/usr/local/tomcat-d-9/bin/catalina.sh line 505: -Djava.security.auth.login.config=: command not found

The WEBAPP repo (line 507) actually exists so I'm confused, also why is it interpreting a url (line 508) as a dir/repo ?
These are only 3 examples of the errors in the log to illustrate the issue, but this is happening for every single JAVA_OPTS in my setenv.sh . It's either :

1. "no such file or directory" : but the file/directory actually exists
2. "no such file or directory" : but it's for a url
3. "command not found" : but it's not a command to run, just a parameter

I'm fairly new to this so I might be missing something obvious. Any idea what could be happening here ?

Here's my edited setenv.sh

#!/bin/bash
COMMON="/usr/local/etc/BashStartFunctions.bash"
[ ! -e "$COMMON" ] && echo "Missing $COMMON" && exit 1
source $COMMON
checkUsr
fetchAppEnv

echo "JAVA_OPTS=$JAVA_OPTS"

EDIT

After the answer of @Olaf Kock, It's now partially working.

The last if in setenv.sh is now the only portion with the error message. I edited the post to show what it currently looks like.

You're splitting up your settings into multiple lines:

-DWEBAPP-CONF-ROOT=/usr/local/webapps-conf/: No such file or directory

does not refer to /usr/local/webapps-conf/ not existing, but -DWEBAPP-CONF-ROOT=/usr/local/webapps-conf/ not existing (obviously)

You can escape the linebreaks using a \, e.g.

JAVA_OPTS="${JAVA_OPTS} \
-Denv=${APP_ENV} \
-Dtomcat.hosts=${TOMCAT_HOSTS} \
....

or

JAVA_OPTS="${JAVA_OPTS} -Denv=${APP_ENV}"
JAVA_OPTS="${JAVA_OPTS} -Dtomcat.hosts=${TOMCAT_HOSTS}"
....

or just write them all in a single line.

Also, consider to use CATALINA_OPTS, rather than JAVA_OPTS.
