hi issy,

this port builds, but doesn't quite work for me (i.e. get minceraft
running). a few issues:

i think the readme should specify that the scripts you wrote are
wrapper-commands, not the java versions themselves? setting it
as a normal java version does not work

when i start a minecraft version, the wrapper command tries to exec
"/usr/local/jdk-21/bin/java /usr/local/jdk-21/bin/java/..." and not
the "/usr/local/jdk-21/bin/java/" part only once. changing this
in the wrapper-script makes minecraft run, at least:

-${JAVA_HOME}/bin/java ${args}
+exec ${args}

however, it will soon complain that it will then complain that it cannot 
find lwjgl:

not sure what the issue is here. i have tried creating both a soft-link
and copying the file to /usr/local/lib/liblwjgl.so. ran ldconfig. didn't
work.

another thing: do you think it's feasible to unveil(2) and pledge(2)
the launcher (and the resulting minceraft process, too)? i have to
admit that i haven't really investigated this, just curious.
