Just use jniThrowException instead. Note that it would be trivial to throw seemingly more appropriate exceptions (NullPointerException and OutOfMemoryException in particular), but I'm only attempting to preserve existing behavior here. I also found shadowing bugs in some of the special-case functions, which would previously always have leaked memory. This also moves an accidental change to a generated file (ActivityThread -> AppGlobals) into the generator, so it won't be overwritten in future. Change-Id: Iab570310b568cb406c60dd0e2b8211f8a36ae590
