InternalError: Error in CachedJarFile entries

Our Java Web Start application (using jar indexing) blocks with the following error when loading a certain jar from the cache. Uninstalling and clearing the webstart cache fixes the problem for one execution, but then the same exception starts being thrown. After the exception has occurred the application often freeze.
