Eclipse can't run Java after recent update on Ubuntu

[Oliver Ruebenacker]

     Hello,

  I'm running Eclipse 3.7.2 on Ubuntu 11.10. Yesterday, I applied some
updates regarding OpenJDK that were offered automatically. I have
installed both OpenJDK 6 and 7. I
still can run Java applications outside of Eclipse, but not in Eclipse
any more. Further, if in Eclipse, I open Preferences and select Java >
"Installed JREs", the view is empty except of the following message:

  "An error has occurred when creating this preference page."

  A separate dialogue opens which says:

"Unable to create the selected preference page.
An error occurred while automatically activating bundle
org.eclipse.jdt.debug.ui (162)."

  The dialogue has a link to an error log, which says:

java.lang.NoClassDefFoundError: Could not initialize class

  Any idea what is going on?

  Thanks!

     Take care
