Tim Allison commented on TIKA-2483:
-----------------------------------
Regression tests in prep for 1.17 show that we need to add quite a few more
specializations of zip and tar to check for and avoid overwriting. Lots of
files that were identified as kmz, tika-ooxml, etc were now being identified as
"zip" during the parse.
Current patch includes list semi-manually, which I abhor, but I added a test to
make sure that PackageParser's list of specialization stays current with
TikaConfig's default config.
After 1.17 is released, we can either work towards getting rid of serialization
of parsers in ForkParser and/or making TikaConfig serializable. Until we do
that, I don't see an elegant solution.

> The mediaTypeRegistry handling code in parse() of PackageParser seems cause
> the problem due to ForkParser cannot properly construct default TikaConfig.
> Also since TikaConfig is not serializable, there is no way to assign
> mediaTypeRegistry/bufferedMediaTypeRegistry before calling parse()
