I'll look into fixing this. Note that the version concerned is a pre-release of IcedTea6 1.11 and not '6b23' which confused me at first (I thought you were referring to a proprietary Oracle JDK).
What disturbs me is that this is not yet in a release of IcedTea6 yet, but you seem to have acquired it via an Ubuntu package.
