In this case, I suspect the NPE is only happening because the code that delivers the first message doesn't return from the method as it should, so it's probably not relevant to diagnosing your issue. Nevertheless, I've raised a JIRA case for the NPE part of this:</div><div><br class=""></div><div><span class="Apple-tab-span" style="white-space:pre"> </span><a href="https://issues.shibboleth.net/jira/browse/SIDP-623" class="">https://issues.shibboleth.net/jira/browse/SIDP-623</a></div><div><br class=""></div><div>Cheers,</div><div><br class=""></div></div><div apple-content-edited="true" class=""><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px;"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; border-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-stroke-width: 0px;"><div class=""> -- Ian<br class=""></div><div class=""><span class="Apple-style-span" style="font-size: medium;"><br class=""></span></div></span></div></span><br class="Apple-interchange-newline"><br class="Apple-interchange-newline">
