JtsGeometry.getBuffered doesn't buffer across the dateline

We are using the getBuffered method to find records that are near the record queried. It doesn't buffer across the dateline, though, so if the query record is next to the dateline, we won't find nearby records properly even though they are geographically close to the query record because the buffered geometry stops at the dateline.

There is a TODO to fix this. Any chance of this being improved? The current implementation is better than the homebrew implementation we were using, in that it at least stops at the dateline rather than generating invalid longitudes, so I am very appreciative of the existing work that's gone in.
