// ZAP: 2011/04/16 i18n
// ZAP: 2012/04/25 Added @Override annotation to all appropriate methods.
// ZAP: 2012/05/02 Removed the method checkAutocomplete(HttpMessage) and a call

// org.zaproxy.zap.extension.pscan.scanner.PasswordAutocompleteScanner.
// ZAP: 2013/01/25 Removed the "(non-Javadoc)" comments.
// ZAP: 2013/03/03 Issue 546: Remove all template Javadoc comments
// ZAP: 2013/05/02 Re-arranged all modifiers into Java coding standard order
