>                 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.
