Hi all
I'm experiencing a problem that seems pretty absurd: I have a complex
GWT app, which spans over several projects; from a while ago (not sure
when it started exactly) the app is loaded successfully and a data
structure is sent over RPC, but, if I reload the page, the *same* RPC
call fails with this exception:
com.google.gwt.user.client.rpc.StatusCodeException: 500 The call
failed on the server; see server log for details

And in the exception message:

or its Class object could not be loaded. For security purposes, this
