WFLYUT0087 error when configuring multiple hosts with unspecified default web module in the EAP 7.1
Issue
The following configuration is working fine in JBoss EAP 7.0:
<host name="www.host1.com" alias="alias1">
<filter-ref name="server-header"></filter>
<filter-ref name="x-powered-by-header"></filter>
</host>
<host name="www.host2.com" alias="alias2">
<filter-ref name="server-header"></filter>
<filter-ref name="x-powered-by-header"></filter>
</host>
but when upgraded to JBoss EAP 7.1, the following error is seeing in the host configuration.:
ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 40) WFLYCTL0013: Operation ("add") failed - address: ([
