Hi Ivan,
test/jdk/java/util/regex/RegExTest.java:
4954: The test should print the failing exception information and
4951: a message if the Pattern.compile does not fail to distinguish that
failure from any others.
I don't think there is a need for so many cases of values > 2^31; there
is no different code path for all those values.
They are fairly cheap, but redundant.
Otherwise, looks fine.
Thanks, Roger

Hello!
When Pattern.compile() parses the repetition count in the expressions
like '.{100}', '.{1,2}' or '.{3,}' it fails to detect numeric overflow
if the result is still non-negative.
Could you please help review the patch?

Also, reading a char at line 3274 is done with skip(), so the
exception thrown at 3315 displays the position of the error more
accurately.
