Priority comparator overflow in CompositeExpressionFactory #1795

What happened:
CompositeExpressionFactory picks the winning ExpressionFactory using a subtraction-based comparator.

.sorted((f1, f2) -> f1.priority(desc) - f2.priority(desc))

What you expected to happen:

This overflows int when a factory uses ExpressionFactory.MIN_PRIORITY/MAX_PRIORITY (which are Integer.MAX_VALUE/Integer.MIN_VALUE), causing the wrong factory to be picked silently, no exception.

How to reproduce it:

Do the previous scenario.
