i'm still using 3.7 with Java 1.6.0_37, not tried with Java 7 yet.
But i encountered some strange behaviour under Mountain Lion compared to Leopard.
When i open an existing project, the project window opens up dramaticaly reduced in size and also remains un-resizable, until i re-attach the 3d-view back to main window.
Note: Most of my projects are saved with detached 3dview.
My projects have been migrated from Leopard (PPC), V3.7 to Mountain Lion (Intel), dunno if this is important.
here's a not very useful grab of the mentioned "smaller" window in original size:
