What does the RI do? :)
I was thinking more about this - can you imagine the confusion if in a
mixed environment of Sun JRE and Harmony JRE, something went wrong that
affected both, and you started getting two different error messages for
the same problem in your logs? How confusing would that be?

Just one more example.
Should users feel comfortable when getting the RI's message
"java.lang.ArithmeticException: Division impossible"?
Isn't it better for a class library to provide
"java.lang.ArithmeticException: integer part of the quotient needs more
than 11 digits"
to help our users find the cause of an exception?

Subject: Re: should strings in exceptions match the reference
implementation?
Yes - great example. The point is for mechanical means, but
familiarity
for users - we don't want them to be "uncomfortable" when using the
Harmony class library - we want it to feel the same as when they use it
from Sun...

not.
I'm not suggesting that code would care if the exception messages are
identical. I was suggesting that it is probably now quite common for
users to type error messages straight in to google. Therefore having
messages match those of existing implementations would help our users
find the cause of an exception.

Are you saying that Classpath does match strings in exceptions?
No. Ah, I see: the "do" in Geir's question stood for "what is
Classpath's
policy wrt to exception messages matching those of the RI?". Then I
don't
speak authoritatively, but I've never noticed Classpath going out of
its
way
to be compatible at this level. But then I would never write code
which
depended on the precise contents of an exception message ...
Sorry for the confusion,
Chris
