Timestamp parsing error

[Jeffrey T Eaton]

I’ve seen a few of these errors in my IDP logs recently:

19:34:32.571 - ERROR [edu.internet2.middleware.shibboleth.common.profile.ProfileRequestDispatcherServlet:89] - Error occurred while processing request
java.lang.IllegalArgumentException: Invalid format: "2014-07-21T23:34:31.25ZZ" is malformed at "Z"
       at org.joda.time.format.DateTimeFormatter.parseMillis(DateTimeFormatter.java:644) ~[joda-time-1.6.2.jar:1.6.2]

I haven’t been able to correlate it to any specific SP sending the request (it would be really helpful if when logging errors, there was a way to connect it back to a specific HTTP request, or something - even just logging the source IP would be a start).

That date format is clearly bad, but does anyone have any advice on debugging what’s sending it?
