Limit Java Heap Space for play framework globaly

by

Play does not appear to pick up the jvm.memory settings for dependencies or even test command. One way to force it to use specific JVM settings would be to use _JAVA_OPTIONS.

For example:

export _JAVA_OPTIONS="-Xms800m -Xmx1500m -XX:PermSize=64m -XX:MaxPermSize=256m"
play test

or

play deps

and you should see

~        _            _ 
~  _ __ | | __ _ _  _| |
~ | '_ \| |/ _' | || |_|
~ |  __/|_|\____|\__ (_)
~ |_|            |__/   
~
~ play! 1.2.3, http://www.playframework.org
~ framework ID is test
~
~ Running in test mode
~ Ctrl+C to stop
~ 
Picked up _JAVA_OPTIONS: -Xms800m -Xmx1500m -XX:PermSize=64m -XX:MaxPermSize=256m
Listening for transport dt_socket at address: 8000

Note that this would apply those settings to all java programs run on that terminal where _JAVA_OPTIONS is set.
