[classlib][regex] Stack overflow when matching over a long sequence

                 Key: HARMONY-5712
                 URL: https://issues.apache.org/jira/browse/HARMONY-5712
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Tim Ellison
         Attachments: TestMatch.java

See the example (attached) which works ok on the RI but fails with a stack overflow exception
on harmony.

The incidence of overflow seems to be related to the distance between the first and last match
("one" and "two" in the example) since reducing the count of "something" strings to 100 makes
the example work ok.

Looks like a better way of tracking the matched subsequences for backtracking is required.
