I have installed Eclipse through the Ubuntu Software Center on my new Ubuntu 11.04 laptop. I tried first using the stock openjdk-6-jdk package with it, but found it crashing on startup, so I removed openjdk6-jdk and eclipse and restarted with sun-java6-jdk package, but still got the same error.

The error from the error log is as follows:

I would say it's related to this bug, which is new and is caused by a kernel revision number that has + in it..

good luck!

Thanks your your answer, but I don't quite see how to fix my issue in that bug report. I do see a reference to a patch, but I don't know how to apply the patch they are talking about. I have run both apt-get upgrade and apt-get dist-upgrade. –  Dave Long Aug 27 '11 at 12:43
    
@DaveLong this is fixed upstream in Eclipse 3.6. –  Rinzwind Feb 23 '12 at 19:08
