Summary: ^([:alpha:]){0,15}$ causes
ArrayIndexOutOfBoundsException
Product: Regexp
Version: unspecified

OS/Version: Windows XP
Status: NEW

RE re = new RE("^([:alpha:]){0,15}$");
boolean match = re.match("test");
This code causes an ArrayIndexOutOfBoundsException if I set the max length to
15 or more. It does not occur if it is less than 15.
It fails with versions 1.4 and 1.5.
