The PMD plugin for JDeveloper has been brought up to date thanks to Torsten Kleiber. Here are the release notes, and you can download the plugin here. From the release notes, it looks like this version of the plugin should work in JDeveloper 11.1.1 Developer Preview 2. Also, you may be able to upgrade the plugin from within JDeveloper itself - there's a new zip file on the update site (http://pmd.sf.net), but I haven't tried that. I'll try to give it a whirl later.
