jvm.options are not respected for Xms, Xmx, and Xmn

 I have a new server that is not respecting my settings for jvm.options. I'm on 7.0.2 SR1, on Linux. When I add the following to the jvm.options: Xms=8GB, Xmx=8GB, Xmn=2GB, it ignores it and appears to override with Xms=4GB, Xmx=4GB, Xmn=1GB. 

The server.startup does not have any settings for it other than in the following stanza: 




When run in a Jazz build, a 32-bit JRE is used, so don't set 64-bit options
if [ -z "$_RUNNING_IN_JAZZ_BUILD" ]; then
    JAVA_OPTS="$JAVA_OPTS -Xmx4G"
    JAVA_OPTS="$JAVA_OPTS -Xms4G"
    JAVA_OPTS="$JAVA_OPTS -Xmn1G"
fi


</pre>
Obviously, this is a server, not a Jazz build. Only if I explicity add the settings to server.startup, will it obey the JVM settings. Any idea why this is happening?

 FYI, removing that stanza allows it to adhere to the settings in jvm.options. Thus, the variable $_RUNNING_IN_JAZZ_BUILD is returning as true when the server is running. This is a defect.
