I use Eclipse Kepler on Ubuntu, which I downloaded and installed separately in /usr/local/eclipse
Last night I upgraded from Ubuntu 13.04 to 13.10, and today all menus (File, ..., Help) are empty. I don't know whether this is a coincidence or has to do with the upgrade. It should not, because I hadn't used the version from Ubuntu's repositories.
$ java -version java version "1.7.0_25" OpenJDK Runtime Environment (IcedTea 2.3.12) (7u25-2.3.12-4ubuntu3) OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
I already tried using a different (empty) workspace and deleting the $HOME/.eclipse directory, but this doesn't help.
Is there any hope I can get the menus back without purging and re-installing the whole thing?
