Throw Exception

I'm just trying out B4J and B4A and I like for obvious reasons to have the ability to throw an exception. From what I can gather, there is the ability to do this in B4A but not B4J. I must admit that this surprises me. It appears to be a trivial task to implement via a Java library item, so all the more reason for my surprise as to why it's not in the core libraries. The Java code is only a one line function. Just want to confirm that I need to create my own very small library to handle this...
