Thanks.  As I said in my previous reply, that doesn't help:

happy:~ $ /local/lambda/build/linux-amd64/j2sdk-image/bin/java  -XX:+UnlockExperimentalVMOptions -XX:+EnableMethodHandles -XX:+EnableInvokeDynamic -cp . Closures

Thanks, but I can't find those at all.  I can find

/local/lambda/langtools/src/share/bin/java.sh-template

which I guess must be what you mean, but no output file.
