It would be interesting to see how an int wrapper would perform on Android.

Note that, as of Android 2.2's Dalvik at least, that Java5 enums are
much much slower than using constants. For anything that gets used
frequently, and that might be used on Android, that is a problem. I
wrote and optimized a SAX and DOM parser on Android. While the JDK
will optimize out most of the overhead for enums and things like
Character objects rather than char, Dalvik won't (yet, as of 2.2 at
least).
Another data point: For small sets with String as a key, TreeMap<> is
much faster than HashMap<>. Makes sense when you think about it, but
it was a surprise at the time.
Just FYI.

That would fall under the Java 5 umbrella, like generics, so that's
OK with
me for an ASAP pool2 release.

Hi all,
in the first pool2 attempt we agreed on replacing numeric/byte
constants with Java5 enums, do we agree on doing it also for first
pool2 release?
Thanks in advance!
