After some updates in my Debian/Jessie installation I run into a strange problem with Eclipse. When I start Eclipse first everything looks fine, but in the moment I use some type-ahead features or browsing classes or methods in a java-file Eclipse crashes without any error message. Maybe the problem is related to an update in libwebkitgtk-3.0.
After some searching I was finally able to fix the problem by adding the following line to my eclipse.ini:
-Dorg.eclipse.swt.browser.DefaultType=mozilla
