Oh, and by the way. Oracle released the 10.1.3.3rd version of JDeveloper a couple of days ago. Looks like it's mostly a bug fix release, but they are certainly nice too, especially now that they have thrown in a few of my favourite BPEL fixes. :-)
In addition, the corresponding SOA Suite upgrade downloads are available: (Windows | Linux).
AFAIK, these links are not yet on OTN, I got them from a forum thread myself, but they seem to be downloading fine, will check the content this week :-)
Alternatively, you can get the patchset from metalink.
