That's perfectly true.
It's also true that dealing with exception specifications in Java
*sucks*. In large Java projects I've worked on the vast majority of cvs
commits end up being maintainance on the exception specifications. It's
just a lot of pointless makework.
Being "not much harder" than Java is no recommendation.
