At the moment I'd use the exception:

    try {
        // exists
    } catch (NoSuchNodeTypeException e) {
        // does not exist

But I agree that a utility method like
NodeTypeManager.hasNodeType(String) would feel nicer for applications
that want to automatically create a node type if it doesn't yet exist.
If you like, a patch for adding such a method to
JackrabbitNodeTypeManager and NodeTypeManagerImpl would be welcome.
Alexander's use of NodeTypeRegistry.isRegistered(QName) is correct.

I'll propose such an addition to JSR 283.
