During Oracle ACE Directors briefing in San Francisco on previous week, Duncan Mills gave JDeveloper 11g Release Candidate for ACE's to test. This build is very close to production they will deliver soon.
What I can say? I really like it, I can't stop testing it during recent days. And, I'm quite surprised in positive way - many bugs from previous builds are fixed, that's good news for us. Main new thing is BEA WebLogic server, its main server now and at least in ACE's build there is no embedded OC4J anymore. Actually, up to some degree I miss good old OC4J. But at the same time, it looks with WebLogic server, application deployment and execution became more stable. WebLogic brings some positive changes in the security area as well, you will see it soon.
One more thing, there will be installer now for JDeveloper. Its related to BEA WebLogic configuration. However, no worries for this, installation process is really quick - up to 5 minutes on my MacBook Pro machine.
Hope you will be able to enjoy JDeveloper 11g production soon.
