Is it just me, or doesn’t anything work in JDeveloper 12c?

Preparing for OpenWorld, I’m updating all my demos to 12c. Unfortunately, my conclusion so far is that nothing works.

The BC tester (now renamed ADF Model Tester) crashes JDeveloper and doesn’t take bind variables. A simple ExecuteWithParams example ignores my parameter value. The list goes on…

Oracle tries to imply some maturity by calling the new JDeveloper, but it feels more like Am I the only one with this experience?

Please comment below or on the 12c thread in the ADF EMG forum.
