Currently, we are using the Java Activation Framework MimeType class.
Currently, when first used, that class takes anywhere between 90-300 ms
to init. I have an alternative implementation that implements pretty
much the same set of operations that takes between 10-20 ms to init.
After the JAF version is init'd, operations on the JAF MimeType take
around 1ms. Operations on my new MimeType take 2ms. So we save a lot in
the init, and lose 1ms afterwards.
There are a few additional differences: my MimeType is more forgiving
and allows characters that are not strictly allowed in MimeType's...
this generally should not be a problem. The match algorithm implemented
by mine seems to be faster.
The MimeType class is not used extensively, but it's init time does have
an overall impact on performance. It's not a big difference but every
little bit counts.
Any objections to switching?

Seeing that MimeType isn't one of those classes that is really widely
used I don't think it matters too much.
Other ugly options: fix the MimeType in geronimo and have people use
that jar. Or, extend MimeType and override all the methods. :-)
