Expected results:
Successful SVG to TIFF conversion

Additional info:
There seem to be two WriteAdapter options that are currently not present on the target architecture: 
- org.apache.batik.ext.awt.image.codec.tiff.TIFFTranscoderInternalCodecWriteAdapter
- org.apache.batik.transcoder.image.TIFFTranscoderImageIOWriteAdapter

Both should be available in batik-codec JAR.
