APAR status

• Closed as program error.

Error description

• When regular expressions are specified in the properties of a
  reference, RPT automatically and silently escapes certain
  special characters such as " and \.  A consequence of this is
  that it is not possible to include characters like an explicit
  newline since \n will always be changed to \\n.
  
  For example, if the regular expression:
  
    "uid":"(.*?)",\n((?!"uid").*\n)*.*"Release Process"
  
  is specified for an added reference when doing manual
  correlation, the Verify button to test the regular expression
  will report that it did not find the highlighted string even
  though it should have.  Likewise, upon playback the regular
  expression will not extract the desired string.
  

Local fix

• As a workaround, custom code can be used since no automatic
  escaping is applied to regular expression in custom code.  Thus,
  when the equivalent regular expression is used in custom code:
  
          String RegExpStr =
  "\"uid\":\"(.*?)\",\n((?!\"uid\").*\n)*.*\"Release Process\"";
          Pattern pattern = Pattern.compile(RegExpStr);
          Matcher matcher = pattern.matcher(args[0]);
  
          if (matcher.find())
              UIDStr = matcher.group(1);
          else
              tes.getTestLogManager().reportMessage("Input does
  not match pattern.");
  
  the custom code will successfully extract the desired string
  from the same response.
