<div dir="ltr"><div>We use the Undertow and XNIO jars which come with Wildfly 10. They are made accessible to the application due to the presence of an Undertow extension. At least, this is my understanding. I would like to avoid embedding later versions of Undertow and XNIO inside the WAR.<br></div><div><div><div><div class="gmail_extra"><br><div class="gmail_quote">2016-06-01 20:35 GMT+02:00 Tomaž Cerar <span dir="ltr"><<a href="mailto:tomaz.cerar@gmail.com" target="_blank">tomaz.cerar@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>On top of my head, it sounds like a bug that was fixed long ago.<br><br></div>Are you sure that code that is throwing this is using latest undertow bits?<br></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Wed, Jun 1, 2016 at 6:13 PM, Thomas Segismont <span dir="ltr"><<a href="mailto:tsegismo@redhat.com" target="_blank">tsegismo@redhat.com</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr"><div>Hi,<br><br></div>Openshift Origin uses Hawkular Metrics to store node and container data. In this scenario, Hawkular Metrics calls the Kubernetes master server over HTTPS to validate the client identity. This is implemented with Undertow Client, as part of a ServletExtension (inside Wildfly 10) [1]. Works fine in development and testing.<br><div><br></div><div>Now the Openshit team sees errors in the logs [2][3]. I couldn't reproduce yet.
