After upgrading to GWT 2.3 some of my RPC services no longer work and
fail with "The response could not be deserialized". It seems to
happen to services that are returning objects that are use Date
objects that are annotated with @Temporal(TemporalType.TIMESTAMP). I
use Gilead 1.3.1 and Hibernate 3.6 and I had no issues with GWT 2.2.
Any idea what could be going on, or how to start debugging?
Here's the stack trace:
