Eclipse freezes on start after upgrade to 13.04

[Magnus]

After upgrading to 13.04 my eclipse freezes when showing the startup splash (with the text "Loading Workbench").

I have a vanilla Eclipse + the Android development tools installed. It worked fine just before the upgrade to 13.04 when running 12.10.

If I remove my workspace I seem to get Eclipse starting, but then there is no Android tools anymore.

Even if the Android tools are to blame, Eclipse not starting at all is a bug of Eclipse I think...

And I have tried with OpenJDK as well as Oracle but the result is the same.

Status changed to 'Confirmed' because the bug affects multiple users.

Can confirm bug. I'm having this problem with Eclipse as well. Also; the Eclipse C++ editor just plain no longer works (clicking on a cpp file in Eclipse now opens gedit instead of the built-in Eclipse editor). What on Earth happened in 13.04?

I ended up installing Eclipse from the eclips webpage instead of from the repo. Then I could install the version 4 which was not in the Ubuntu repo.

I can also confirm this bug and would like to see it fixed.
However, I have no clue on where to start. If someone could provide me some instructions I will gladly investigate some more.
