Deprecated SerializableException

[rjcarr]

I'm attempting to upgrade to GWT 2.0 and everything is working well
enough except I am getting this warning in the compile step:

Referencing deprecated class
'com.google.gwt.user.client.rpc.SerializableException'

And the file it mentions is a gwt derived file with the suffix:
_TypeSerializer.java

The warning always happens on service classes (i.e., RemoteService),
but doesn't seem to happen on *all* service classes.

I have not defined SerializableException explicitly, but my method
signatures do throw Exception.

Any idea why this is happening and what I can do to make it go away?

Thanks!

I've been wondering about that too....

If your method throws Exception, or a custom class that extends
Exception, then you will get this warning. Maybe because the GWT
compiler searches for all subclasses of Exception, and finds
SerializableException. It includes it in the list of serializable
types, and you get a deprecation warning. I don't know how to make it
go away, without going back to 1.7.

> a custom class that extends Exception

That must be it; we have a couple of custom classes that just extend
Exception:

./InitializationException.java:public class InitializationException
extends Exception
./RPCException.java:public class RPCException extends Exception

Would we be better off using one of the Exception types that GWT
emulates? Or is this just an annoying-but-harmless warning?

Actually, I tend to *only* use Exception for my remote service methods
and I still get the warning.

[Brian Dorry]

Has anyone found a solution to this? I haven't experienced any runtime
problems ignoring these messages but I'd like to follow a newer
standard if it exists.

Your methods should throw SerializationException agains Exception.
