<div dir="ltr">Thanks for helping us out here. I've filed <a href="https://issues.jboss.org/browse/WFCORE-4674">https://issues.jboss.org/browse/WFCORE-4674</a> and I think I've got a fix for it. The one caveat is the fix will be in a the log manager with a slight hack in JBoss Modules. That also means once fixed in those two projects releases and upgrades will be required.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Sep 18, 2019 at 12:28 PM Dustin Kut Moy Cheung <<a href="mailto:dcheung@redhat.com">dcheung@redhat.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Yup I do have some logging stuff:</div><div><br></div><div>-Xbootclasspath/a:/opt/eap/modules/system/layers/base/.overlays/layer-base-jboss-eap-7.2.3.CP/org/jboss/logmanager/main/jboss-logmanager-2.1.7.Final-redhat-00001.jar:/opt/eap/modules/system/layers/base/org/glassfish/javax/json/main/javax.json-1.1.2.redhat-1.jar:/opt/eap/modules/system/layers/base/javax/json/api/main/javax.json-api-1.1.2.redhat-1.jar:/opt/eap/modules/system/layers/base/.overlays/layer-base-jboss-eap-7.2.3.CP/org/wildfly/common/main/wildfly-common-1.5.1.Final-redhat-00001.jar</div><div><br></div><div>The additional files that I add to the modules folder is here:</div><div><br></div><div><a href="https://paste.fedoraproject.org/paste/y2xf5u5nq3iL18pQOkAlNQ" target="_blank">https://paste.fedoraproject.org/paste/y2xf5u5nq3iL18pQOkAlNQ</a></div><div><br></div><div>Let me know if I should create an EAP or a Wildfly issue!
