playframework - Limit Java Heap Space for play framework globaly

I have a very old linux system and installed java and play framework. When I run java I get:

java -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

So I limited the java heap space in application.conf:

jvm.memory=-Xmx256M -Xms256M

With that setting I can run play test, play run etc....

But I cannot run:

play dependencies 
~        _            _ 
~  _ __ | | __ _ _  _| |
~ | '_ | |/ _' | || |_|
~ |  __/|_|\____|\__ (_)
~ |_|            |__/   
~
~ play! 1.2.1, http://www.playframework.org
~
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

Is there a global configuration file or environment variable where I can limit java heap space globaly for play framework?

Update: Also the following is not working:

play dependencies -Xmx256M -Xms256M
~        _            _ 
~  _ __ | | __ _ _  _| |
~ | '_ | |/ _' | || |_|
~ |  __/|_|\____|\__ (_)

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.
