Oracle joined the Eclipse foundation reluctantly and they have, as far as I know, not released an IDE based on Eclipse.
JDeveloper is more targeted for RAD development or development for software to run on Oracle software (such as JHeadstart) - although JDeveloper is certainly not limited to Oracle software. By the way, JDeveloper is based on a old version of JBuilder (I think it was JBuilder 2)
I, as many programmers, like Netbeans more then Eclipse, so changes are big Netbeans will get (more) support of Oracle.
