WFLYUT0087 error when configuring multiple hosts with unspecified default web module in the JBoss EAP 7.1/7.2

Solution Verified - Updated -


The following configuration is working fine in JBoss EAP 7.0:

<host name="" alias="alias1">
    <filter-ref name="server-header"/>
    <filter-ref name="x-powered-by-header"/>
<host name="" alias="alias2">
    <filter-ref name="server-header"/>
    <filter-ref name="x-powered-by-header"/>

but the following error is seeing in the host configuration after upgrading to JBoss EAP 7.1.x/7.2.x:

ERROR [] (ServerService Thread Pool -- 40) WFLYCTL0013: Operation ("add") failed - address: ([
    ("subsystem" => "undertow"),
    ("server" => "default-server"),
    ("host" => "")
]): java.lang.IllegalArgumentException: WFLYUT0087: Duplicate default web module 'ROOT.war' configured on server 'default-server', host ''
