Java version

What version of Java is z-training using to compile and grade our submissions? It'd be nice if this were posted in the Java grading explanation page.

1.6

I'll post it

I'm using java.util.Scanner and also java.math.BigInteger ... are these allowed? Those classes are not listed in the exception list.

Looks like I got consecutive compile errors. Do you send compile error messages via email or somehow show it somewhere in this site?
