I assume lots of Fosstrak users are also using the LLRP Toolkit for Java that was originally developed by the Fosstrak team and contributed to the LTK project. We just released a new version of the LTK for Java that is now available from sourceforge. The new release features a number of bug fixes. See the changelog for details.
