Hey Gang, I hope someone is able to shed some light on this issue I'm
having.
We are currently using GWT 1.7.1 to compile our GWT applications.
Everything is working fine with GWT 1.7.1, as a note. I've been
tasked with updating us to 2.0.3. To give a little background we're
using "generate-with" in our module xml files. We have a tag
interface "Exportable" that we use on interfaces to generate DTO
objects so we don't have to manage a true Model object and a DTO
version of it. We've looked at other ways of doing this in the
future, but for now we're stuck with what we have.
The issue I'm running into is during our ant compile of our gwt
projects. During the compile of one of our modules we get to the point
where we're walking the object graph "Analyzing the fields of type
'...' that qualify for serialization". The next thing we get is the
following error message:
"Checking type argument 0 of type 'java.util.Arrays.ArrayList<E>'
because it is exposed as an array with a maximum dimension of 1 in
this type or one of its subtypes (reached via
XX.client.ISubjectRecord)". NOTE I substituted our full package name
with "XX". This message is repeated about 50 times. Then messages
what follows is about 8000 lines of messages like this:

As part of the messages is also our code, but what boggles me is that
a large number of GWT code classes are also showing this error.
