A lot of existing code in Java bindings catches exceptions just to silence them later. This is: a) Unnecessary: it is OK for a function to throw a RuntimeException without declaring it. b) Highly unidiomatic and not recommended by Java experts (see Effective Java and others) c) Confusing as has the potential to hide the existing bugs and have them resurface at the most inconvenient/unexpected moment.
