java.lang.OutOfMemoryError: Java heap space

Lately, I have to process a big pdf file with java  and I always get this error.

To solve this, add these arguments

“-vmargs -Xms1024m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=128m”

when you run your java program.

Ex java MyGUI -vmargs -Xms1024m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=128m

For more detail information, try this link.
