eclipse - An internal error occurred during: "Loading bundle[...]"

Question

I've started using Eclipse Luna with the plugin Aptana Studio 3 and it worked quite well for a while, but after I ran Eclipse as root to update the IDE to version 4.4.1, every time Eclipse starts I get the following error message:

An internal error occurred during: "Loading bundle: /opt/eclipse/configuration/org.eclipse.osgi/873/0/.cp/bundles/php.ruble". org.eclipse.osgi.internal.framework.EquinoxConfiguration$1 cannot be cast to java.lang.String

I get this error message for the other Aptana bundles as well.

I've tried reinstalling Eclipse and Aptana Studio but nothing has worked yet. I'd be very glad if someone could help. Sorry for bad english, I'm not a native speaker.

Here's a log sample:

!ENTRY org.eclipse.core.jobs 4 2 2014-09-27 19:19:23.753

I had the same issue. Building from the previous post, and in case it was missed, the Eclipse team has already provided a patch:

Steps to apply patch:

1. Open Eclipse > Help > Install New Software
2. In "Work with:" field, enter http://download.eclipse.org/eclipse/updates/4.4/
3. From the populated list, select Eclipse 4.4.1 Patches for bug 445122 . Click "Next"
4. Let Eclipse perform the needed checks. Click "Next"
5. In "Install Details" screen, click "Next"
6. Finish the patch installation process and restart Eclipse.

The problem on my Eclipse was gone after this. In Win7 I am using: Eclipse IDE for Java Developers Version: Luna Service Release 1 (4.4.1) Build id: 20140925-1800
