Fails with all Sun's JDK and OpenJDK.

It seems like fop throws this error if the dataType is not TYPE_BYTE or
TYPE_INT. This is a bug with the sources; I will file this upstream.

org/apache/fop/pdf/AlphaRasterImage.java:

143 //...and write the Raster line by line with a reusable buffer
144 int dataType = alpha.getDataBuffer().getDataType();
145 if (dataType == DataBuffer.TYPE_BYTE)

{ 146 ... 151 }

else if (dataType == DataBuffer.TYPE_INT)

{ 152 .... 168 }

else

{ 169 throw new UnsupportedOperationException("Unsupported DataBuffer type: " 170 + alpha.getDataBuffer().getClass().getName()); 171 }

Should handle other datatypes. See bug initially reported here: https://bugzilla.redhat.com/show_bug.cgi?id=461740
