Does OpenJDK support bitmap image with JarURLConnection?

[Chris Hegarty]

Interesting... I would have guessed bmp would be supported too.  It
doesn't appear to be specific to JarURLConnection, raw file urls also
exhibit the same behavior.

Wow, last time content-types.properties was meaningfully changed was
1999, when PNG was added! I don't have any specific objection to adding it.
