I'm fine either way (I believe even some classes in the JDK have some
[unchecked
exceptions](http://hg.openjdk.java.net/jdk7/jdk7/jdk/file/9b8c96f96a0f/src/share/classes/java/util/LinkedList.java)
declared?)
But I suspect this change is not backward compatible. Can't locate that
documentation from Oracle explaining what's a backward change or not, but quite
sure this one is.---
