Mateusz, So you're saying the Geotiff specification describes how to handle the case where files cross UTM boundaries?

You need to follow GeoTIFF specification in this regard. libLAS links to libgeotiff to access GeoTIFF features necessary to handle CRS/SRS. libLAS does not implement GeoTIFF specification itself - it would be a big and painful task :-) So, it's very reasonable to use libgeotiff. I'd suggest to follow the same approach and try to find GeoTIFF implementation in Java or perhaps there is Java binding for libgeotiff available.
