After your comment I purged the eclipse package and the gcj package and reinstalled both. The problem remains the same.
I have Ubuntu with the kubuntu-desktop installed and I upgraded to 7.04 about one week ago. I installed all the last updates. KDE: 3.5.6-0ubuntu17 eclipse: 3.2.2-0ubuntu1 gcj: 4:4.1.2-1ubuntu1 -- [Feisty] Eclipse starts up but crashes on first click https://launchpad.net/bugs/95352 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
