Exception: Inconsistent Storage

When I am starting the project I am coming across the following exception.

org.netbeans.javacore] INFORMATIONAL *********** Exception occurred ************ at 1:24 PM on May 3, 2007

java.lang.RuntimeException: Inconsistent storage. (mdrList.size == 0, infos.size == 44)

any clues will be helpful

Thanks
