test_valve.jar and TestWAR.war and config files

Description of problem:
With "-Dorg.apache.tomcat.util.ENABLE_MODELER=true", server level MBeans like a global valve become available. Those should be visible from start phase of a web app, though sometimes those are missing and javax.management.InstanceNotFoundException is thrown.


How reproducible:
This sporadically happens due to the parallel nature of WildFly start up. It is reproducible by using a debugger (Eclipse is better than JDB, because JDB stops all threads).


Steps to Reproduce:
Follow the steps described in WFLY-3557.  Here is the summary of it.
1. Unzip attached sample.zip onto $JBOSS_HOME of EAP 6.1.1.
2. Set break point at org.apache.catalina.core.ContainerBase:1203.
3. Start the server.


Actual results:

Expected results:
MBean "jboss.web:name=TestValve,type=Valve" should be available in start() method of TestValve2.


Additional info:
WildFly 8+ replaced the web server with Undertow so the reproducing steps are not applicable to the recent upstream versions.
