This is not a bug.

Infinity is not supported by JSON.

See section 2.4 of the RFC

http://tools.ietf.org/html/rfc4627

I don't see any reason why the JSON package couldn't support Infinity though. I 
had
to add Infinity and -Infinity for a project which was sending me data over a
webservice in JSON format. I had to build it in - so why can it not be built in 
by
default? My JSON Class is now more fully featured as a result.
