      Tomcat fails to start when using JAVA_OPTS which have spaces in them. This is a known issue in JBoss Web Server 3.1.0.

      Description of problem:

      The Tomcat start scripts do not seem to parse or processes JVM values that contain spaces correctly.

      Version-Release number of selected component (if applicable):
      JWS 3.1.0: tomcat7-7.0.70-16.ep7.el7.noarch

      How reproducible: 100%

      Steps to Reproduce:
      1. Install tomcat7
      2. Set an env loaded by the JVM (that contains a space) in /etc/sysconfig/tomcat7

      JAVA_OPTS="-XX:HeapDumpPath='/tmp/foo bar biz bang.heapdump' -XX:+PrintFlagsFinal"

      3. Restart the application

      Actual results:

      Tomcat starts with: 

      [root@rhel7 ~]# systemctl start tomcat7
[root@rhel7 ~]# systemctl status tomcat7
● tomcat7.service - Apache Tomcat Web Application Container

      Expected results:

      Tomcat should start without an issue and dump a list of all JVM flags to stdout (which you can check with journalctl -u tomcat7).

      Additional info:

      Using various "", '' (quoting structures) or \ (escape characters) do not seem to enable the ability to load environment variables with spaces in them (to the JVM).

      It should be noted that "spaces" in JVM parameters are possible, however they do not seem to be possible in the Tomcat EWS start scripts.
