Unix shell startup script setenv.sh doesn't set PermGen option

As can be seen in this thread the setenv.sh is not correct in the standalone distribution of 4.1.1

There are a lot of variables that somehow are not escaped right and therefore do not affect the memory setting at all.
Perm gen stays at 84 MB and therefore the script terminates with out of memory errors.

With a simple string like this (instead of the large script) it could be sorted out:

JAVA_OPTS="-Xms128m -Xmx512m -XX:MaxPermSize=256m -Dfile.encoding=UTF8 -Djava.awt.headless=true -Datlassian.standalone=JIRA -Dorg.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER=true -Dmail.mime.decodeparameters=true"

export JAVA_OPTS

We had a similar problem already in 4.0 see below....

--------------------

If the standalone JIRA is installed under path consisting the space character e.g. "/opt/support applications/atlassian-jira-enterprise-4.0-standalone"

The setenv.sh script fails to set correctly the installation path variable "PRGDIR" and in the same time detect the JVM type.

As the result of this bug the JVM is set with the default amount of memory assigned to PermGen by Tomcat - 64MB!

Since for JIRA 4.0 requires much more memory, in matter of minutes the application crashes with "javax.servlet.ServletException: PermGen space"

We should escape variables in the following places

PRGDIR=`dirname $0`					      |	PRGDIR=`dirname "$0"`
JAVA_OPTS="-Xms128m -Xmx256m $JAVA_OPTS -Djava.awt.headless=t (

    if [ $JAVA_PERMGEN_SUPPORTED = "true" ]; then	      (
