Failure to load login-module should be reported as WARNING instead of TRACE

An error in standalone.xml :
<security-domains>
<security-domain ...>
<authentication>
<login-module code="database" flag="required">

is reported in TRACE:

TRACE [org.jboss.security.authentication.JBossCachedAuthenticationManager] (http--127.0.0.1-8080-1) Login failure: javax.security.auth.login.LoginException: unable to find LoginModule class: database from [Module "deployment.jboss-as-login.war:main" from Service Module Loader]

It makes it difficult to spot the error.
Would be easier if it was reported as a WARNING, specially since it is "required"
