Certificate Expiration Validation fails with non-English locale



On configuring an Authentication Service with signing certificates, the Certificate Expiration validation fails at runtime with an invalid Date exception.

Error Messages

Unable to process the SAML WebSSO request : Exception in parsing the expiry date to stringUnparseable date: %22Wed Oct 23 14:26:00 UTC 2019%22

Steps to Reproduce

Review Step 9 of the pySAMLWebSSOAuthenticationActivity which manipulates the Date in String format. This fails if the and the user.language are non-English.

To simulate, use the below code to create the activity with the Java step:

String pyIDPSigningCertificateExpiry = "Thu Mar 09 13:27:30 UTC 2028";
String pySPDecryptionCertificateExpiry = "Wed Oct 23 14:26:00 UTC 2019";
String sigexpirydate = pyIDPSigningCertificateExpiry;
String decexpirydate = pySPDecryptionCertificateExpiry;
java.util.Date currentDate = new java.util.Date();
java.util.Date expiredDateSignature = new java.util.Date();
java.util.Date expiredDateDecryption = new java.util.Date();
try {
//            java.util.Locale locale = new java.util.Locale("nl", "NL"); // if you uncomment this line then we get an error
            java.util.Locale locale = new java.util.Locale("en", "US"); // if you uncomment this line then the parsing is correct
            expiredDateSignature = new java.text.SimpleDateFormat("E MMMM d HH:mm:ss z yyyy", locale)
            expiredDateDecryption = new java.text.SimpleDateFormat("E MMMM d HH:mm:ss z yyyy", locale)
            oLog.infoForced("t1: " + expiredDateSignature);
            oLog.infoForced("t2: " + expiredDateDecryption);
        } catch (java.text.ParseException e) {
            oLog.infoForced ("ex: " + e );
        } The code works for en_US. However, it fails for nl_NL.
