Bug#490621: libbatik-java: rasteriser doesn't recognise OpenJDK as a valid Java install

  I'm afraid it is slightly more complicated than it seems:

  * first, JPEG compression does not work with openjdk:

JAVA_HOME=/usr/lib/jvm/java-6-openjdk rasterizer -m image/jpeg FirstTry.svg
About to transcode 1 SVG file(s)

Converting FirstTry.svg to FirstTry.jpg ... ERROR: The JPEG quality has
not been specified. Use the default one: no compression
Exception in thread "main" java.lang.IncompatibleClassChangeError: Found
class com.sun.image.codec.jpeg.JPEGEncodeParam, but interface was expected

        at org.apache.batik.apps.rasterizer.Main.execute(Unknown Source)
        at org.apache.batik.apps.rasterizer.Main.main(Unknown Source)

  [ that is the only one, however, the rest seems to be fine ]

  * second, batik 1.6 refuses to build with anything else than sun's
java 1.4, for reasons which escape my poor understanding of the various
flavors of java runtimes, which alone is enough to keep it from main.

  So this won't be easy to fix... Batik 1.7 might help, but there are
other problems at the moment, including the fact that its interface has
changed a fair amount and that I fear for its reverse dependencies.

  Cheers,
