Jim,
Apparently the workaround I suggested the other day wasn't the best one, as
it allowed you to compile but then failed at match-time.
This new fix seems to work OK in both java.util.regex and org.apache.regexp:
^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][\-\w]*[0-9a-zA-Z]\.)+[a-zA-Z
]{2,9})$
My guess is that [-\w] and [\w-] are either not well defined or mishandled
by regexp; in either case escaping the hyphen takes care of (or avoids) the
problem.
Interestingly regexp did accept [-.\w] ...

Pattern class
I ran through a bunch of unit tests to validate that the RE compiled pattern
operated the same as when compiled with either ORO's Perl5Compiler or Java's
Pattern. I found that in one instance it did not:

I'd expect this pattern to fail the match and it does for ORO and Java. But
it
passes when run through Apache regexp. The pattern as amended is:
^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][\w-]*[0-9a-zA-Z]\.)+[a-zA-Z]
{2,9})$
