The variable sun.text.normalizer.NormalizerImpl.canonStartSets
was discovered to be 16k Objects, almost all of which are null.
I can't find any use of this array in the JDK, except to fill in the
first four elements. Perhaps it could be eliminated,
or perhaps

    static final int CANON_SET_MAX_CANON_SETS = 0x4000;
should be
    static final int CANON_SET_MAX_CANON_SETS = 0x4;
