Eclipse does not compile code using Sun's compiler ("javac"); it has its
own entirely separate compiler implementation. It does not provide its
own JVM ("java") or java-standard-library implementation (rt.jar etc).
So it is no surprise to find that eclipse's compiler works where the sun
java compiler crashes (and vice versa).
This is just a sun javac bug that your code has triggered, and nothing
to do with Maven. This has happened to me half-a-dozen times in
half-a-dozen years.
