Quotes are OK. It is shell scripting, not Windows one.

What is not OK:
1. The statement inside of "if" executes only if $JAVA_OPTS is empty.
Is it empty?
2. Learn the difference between JAVA_OPTS and CATALINA_OPTS variables.
 You should not put such a value into JAVA_OPTS. You should not put it
info both variables at the same time.

Have you tried to search the archives of this mailing list?
