Getting back into indy...need a better argument collector!

[Jorn Vernee]

Hi Charlie,

(Sorry for replying out of line like this, but I'm not currently 
subscribed to the mlvm-dev mailing list, so I could not reply to your 
earlier email thread directly.)

I have fixed the performance issue with asCollector you reported [1], 
and with the patch the performance should be the same/similar for any 
array type (as well as fixing a related issue with collectors that take 
more than 10 arguments). The patch is out for review here: 
https://github.com/openjdk/jdk/pull/3306

Cheers,
Jorn
