JVM Language Summit Examples

[Doychin Bondzhev]

Looking at code for pow I think there is something wrong here.

It could be my mistake but this looks like recursive call of pow from pow.
So in case of x and y not in any of the special cases this will result in
stack overflow. Probably on the last line of call to pow should be Math.pow
instead of just pow.
