Did I understand correctly that it's a Java application? If so, how are you launching/running it? What CLI command you using?

Oh i know they use a whole file for those arguments, ill see if i can check that and get back to you, what I can recall currently is- xms 512 and -xmx 2028

Is that enough memory to start the java application? That means you are starting it with 512MB of RAM and giving it a max of 2028 MB.
