> LUCENE-4876 changed the IndexDeletionPolicy to an abstract class. The
> SolrDeletionPolicy extends this class but overrides the onInit and onCommit
> methods with non generic parameters. This makes people who extend
> SolrDeletionPolicy (even though we don't recommend doing that) run into a
> Java6 bug:
> http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6775192
> The workaround is to use reflection to call the parent class's method. I
> propose that we change SolrDeletionPolicy to override parent's methods with
> the exact signature.
