I've been meaning to pose a related question.

Why is it that in /usr/ports/Mk/bsd.java.Mk java/diablo-jdk15 is
preferred over java/jdk16? In fact the order of preference seems to be:
diablo-jdk16, diablo-jdk15, openjdk6 then jdk16 ...

I alluded to this curiosity in my recent post to freebsd-eclipse@ "java
process doesn't terminate after exiting eclipse". With the two
aforementioned java ports installed then by default:

        %java -version
        java version "1.5.0"
        Java(TM) 2 Runtime Environment, Standard Edition (build diablo-1.5.0-b01)
        Java HotSpot(TM) Server VM (build diablo-1.5.0_07-b01, mixed mode)

and I must set JAVA_HOME or, as I have now done, add to /etc/make.conf:

        JAVA_PREFERRED_PORTS?= JAVA_PORT_NATIVE_BSDJAVA_JDK_1_6

to get java/jdk16.

Using textproc/fop recently with both port versions I've noticed that
fop generally runs around 25% faster with java/jdk16.

I also seem to recall having read statements to the effect that the
java/diablo-jdk ports are "less functional" than the java/jdk ports
making the preference given to the former all the more curious.
