jpackage and java.lang.OutOfMemoryError: Java heap space

[Tomisław Kityński]

Hello,

I've been trying to run jpackage with different heap sizes, as I get 
exception as in the subject from jlink:

java.io.IOException: jlink failed with: Error: Java heap space
java.lang.OutOfMemoryError: Java heap space

e.g. with -Xmx4g or -Xmx:4g, but i get Error: Invalid Option: [-Xmx4g].

What can I do to increase heap size?

Greetings
