Andrey Razumovsky closed CAY-1331.
----------------------------------
Resolution: Fixed
Fix Version/s: 3.1M1
OK, I'm desperate to get an answer from Hessian team, so I've done a workaround
which works with Hessian 3.0.x, 3.1 x and 4.0.x. Note that Hessian 3.2.x is
binary incompatible with our code.
This is only committed to 3.1 branch, as the workaround will hopefully be
removed after Caucho fixes the problem (Cayenne 3.0 will be frozen by that
time). If you want to, you can pick svn patch and build custom version of
Cayenne
BTW maybe we should start test against Hessian 4.0.2 internally? Andrus, do you
think new artifact should be deployed to Objectstyle repo or we can add caucho
repo to our pom?
