This file is in a package that also contains some JNI, so it is
Architecture: any.  I could split the JNI and jar into two packages,
but it really doesn't seem worth it, two packages, tightly coupled,
each with one small file.

Is it reasonable to build or repack a jar file deterministically?
Something like this, to normalize file timestamps and ordering?

    mkdir TMP
    unzip $jarfile -d TMP
    find TMP -exec touch 198001010000 {} +
    (cd TMP; find | sort | xargs zip -9 ../TMP.zip {} +)
    mv TMP.zip $jarfile
    rm -fr TMP

Is this what I should do?
