[SOLVED] Java Error When Starting Eclipse

Issue

Every time I start Eclipse on my laptop running Fedora 20, a new log file is created in the same folder where Eclipse was started with a name like abrt_checker_xxxx.log where xxxx is a different 4-digit number. Inside the log file there is always the same error:

Uncaught java.lang.ClassNotFoundException exception in thread "main" in a method java.lang.ClassLoader.loadClass() with signature (Ljava/lang/String;Z)Ljava/lang/Class;
Exception in thread "main" java.lang.ClassNotFoundException: .home.raffy.eclipse..plugins.org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar

This happens when running Eclipse on both OpenJDK 7 and Oracle JDK 7. It did not happen when I had Fedora 19 with the same exact set up.

Solution

I was able to eliminate the symptoms only (the log file being created after every Eclipse start) by removing a package called abrt-java-connector from Fedora.

sudo yum remove abrt-java-connector

Like I said, this only removes the symptoms. The underlying problem is either with Fedora 20 or Eclipse and hopefully can be resolved in future versions.

The problem is not related to my set up because I was able to recreate the same problem by doing a fresh install of Fedora 20 and a fresh install of Eclipse on a completely separate laptop.
