I don't believe that my proposed change in any way conflicts with the
status quo. If the property is defined, tzdata is read from the value of
the property. If the directory is not valid (or ZoneInfoMapping doesn't
exist) or if the property is otherwise undefined or invalid, it is
simply ignored, and the JDK-supplied tzdata is used instead. [Although I
admit, allowing this property to change makes me nervous. I would rather
it ALWAYS use the system data or NEVER use it -- rather like how OpenJDK

I don't think Microsoft would ever release tzdata for use by Sun's JRE,
but I could just be pessimistic. O:-) The only hosts that this really
affects are Solaris and Linux.

While our (Red Hat) hands are tied, of course, I would not agree with
the decision to turn this off by default, effectively ignoring the
problem that the patch is attempting to address.
Is there really no solution to this problem?
