self intersecting polygon errors

Hi, trying to play with polygon searches and have noticed this issue. It
seems when you cross a line you invalidate the polygon (Sorry I have no idea
about the technical term) and solr cannot handle it.

As far as my google fu goes, there is no fix, its not specific to solr, its
to do with geometry moreso.

Anyone have a work around? Could this be fixed or should I just try and
control this at the customer front end script to check if the shape is
valid.

Using Solr4 and I think current version of JTS (downloaded/installed in mid
November).

Thanks
