Sorry about that... Hit return too soon. Here's lowest part of the stack
trace:
Caused by: java.lang.NullPointerException

That corresponds to this line in BeanUtil:
qNamefortheType = typeTable.getQNamefortheType(
beanObject.getClass().getPackage().getName());
So it's trying to look something up... Maybe the type of the class it's
trying to return? The same exception is triggered on double[][] and
double[][][] return types, but not double[].
I'll dig into this more later.
