java.lang.OutOfMemoryError: Java heap space

Hi, I got this error when I was trying to train a font with a language model trained on large corpus (over 200MB). The language model created is around 43MB and the initialized font is around 57MB. I have no problem using the software with a smaller size corpus. Any idea how to fix the problem?

You should be able to give the JVM more heap space with the -Xmx flag.
