Eclipse Juno - toolbar spaces after upgrade

Question

I just updated the Eclipse IDE plugin for Java developers to version 1.5.1.20121004-1506 , which led to ridiculous spaces in the main toolbar:

Yes, I know that it’s basically a bad idea to upgrade Eclipse with past Indigo, because each new version looks worse and worse, but is there an easy way to fix this, except to reinstall some older version (I really don’t know t want to lose my settings and installed plugins)? Is this bug tracked somewhere?

Answer 1

In my case, this happened because I opened the workspace in the Eclipse version, which skipped some of the plugins of the previous Eclipse installation (in fact, it was STS before and simple Eclipse J2EE afterwards). Creating a new workspace and importing all projects fixed the problem for me.

Try moving to the Classic theme and restarting. He works on Mars.
