Hello Vincent,

thanks for reporting this issue. Actually the capturing index starts from 1, not 0.

Best regards,
Thierry Boileau

When you reuse a variable in a template (e.g. router.attach("/{p1}/{p1}/foo",MyResource.class);), you get this exception when you try to GET the URI: java.util.regex.PatternSyntaxException: Illegal octal escape sequence near index 90 /((?:[a-zA-Z0-9\-\.\_\~]|\ [ -- stuff deleted --] +\,\;\=]|\:|\@)+)/\0/foo ^

Apparently, util.regex doesn't like the '\0' you're adding to the regexp when a variable is reused.
