Can I pass arguments to the Java VM with JNLP Wrapper?
Yes! The JNLP specification only allows you to pass minimum and maximum heap sizes to the Java VM, but JNLP Wrapper enables you to pass any arguments you desire. To do so, see -jvmarg on the Arguments page. For example, if you want to turn on incremental garbage collection and you know you’re using a JVM that supports it, you can specify -jvmarg -Xincgc in the arguments section of your JNLP file.
