http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22997 RE throws ArrayIndexOutOfBounds when grouping repetition is >= 16 Summary: RE throws ArrayIndexOutOfBounds when grouping repetition is >= 16 Product: Regexp Version: unspecified Platform: All OS/Version: All Status: NEW Severity: Normal Priority: Other Component: Other AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] For the following code snippet: String s = "1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 "; org.apache.regexp.RE re = new org.apache.regexp.RE("([0-9]+ ){17}"); System.out.println(re.match(s)); Basically i have a string s that consists of a number followed by a whitespace, repeated 17 times. To verify this pattern, my RE uses "[0-9]+" to denote the number, followed by a whitespace " ", and the 2 are grouped by "()", then followed by the repetition operator {n} (shown above n=17). The match result should be "true" for n=1 to 17. it does return "true" if you start n from 1 and increase all the way to 15. But as soon as n >= 16, an ArrayIndexOutOfBounds will be thrown with the number "n", which seems to indicate some hard-coding of capacity somewhere in the code. I tried this on both REGEXP 1.2 and 1.3. same results. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
