------------------------------------
Hi Sergey,
Thanks for the commits. I did some more digging (in a Java SE environment),
and it looks like there really isn't a huge gain in using str.split() vs the
current approach. I'll attach the test case I used and the results. Using
str.split() did seem faster when parsing more media types, but the difference
is minor.
Thanks, Andy
