You use a Matcher to match. A Pattern is only the compiled form of a regex:
final String re = "^";
final Pattern p = Pattern.compile(re);
final Matcher m = p.matcher("myinput");
if (m.matches())
// etc
So, the fact that Matcher instances are not thread safe is not really
the problem.

Agreed. The Tomcat documentation also suffered the same problem (wrt
regex usage in its <regex-mapper> IIRC) and I've had the doc fixed :p
