Does anyone know how a class F TIFF file could be generated in order to be decoded with JAI?

The TIFF files generated in this way are viewable using ghfaxviewer or okular, but I get a runtime exception when using JAI. Any ideas?

Below is the error I get using my java app:

java.lang.RuntimeException: Invalid code encountered while decoding 2D group 4 compressed data.
