When I try to launch JBDS from the installer, which I run with Java 7, after choosing a workspace (using a clean workspace btw.) the 'loading' splash disappears shortly after it shows up (and the progress bar is still somewhere around the beginning).
Then a blank JBDS window appears and about 10 - 20 seconds later a 'Not Responding' dialog appears followed by the rest of JBDS right away.
