Summary: Confusing Error Message when main Method not static

Initial Comment:
When a program with a main method that is not static is run, DrJava prints a confusing error message when the "run" command is used. It works with the "java" command.

Welcome to DrJava.  Working directory is D:\Documents\Dev\Java
> run Lab
java.lang.NullPointerException
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
	at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
	at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)
	at java.lang.reflect.Method.invoke(Unknown Source)
	at edu.rice.cs.drjava.model.compiler.JavacCompiler.runCommand(JavacCompiler.java:271)
> java Lab
Static Error: No method in static Lab has name 'main'
