When the http.nonProxyHosts property value contains quotes they are not escaped properly and /opt/amq/bin/env reports syntax errors

ERROR: There are syntax errors in '/opt/amq/bin/env'

Looking at this file, it contains jvm options that are generated by the launch.sh script:

sh-4.2$ cat env

As you can see, the http.nonProxyHosts property value contains quotes, which should be escaped when used in a shell variable assignment, if the assignment itself is also inside quotes.

I tracked the problem to the script /opt/run-java/proxy-options, where the nonProxyHosts are created with quotes. By adding another pair backslashes to escape the quotes when the variable is used, I was able to work around the problem.

before (proxy-options line 45):
ret="$ret -Dhttp.nonProxyHosts=\"$(echo $noProxy | sed -e 's+,+|+g')\""
after:
ret="$ret -Dhttp.nonProxyHosts=\\\"$(echo $noProxy | sed -e 's+,+|+g')\\\""
