Description of problem:

When starting with -Dorg.apache.catalina.connector.WAIT_FOR_BEFORE_START set, an exception like the following can be seen randomly at start up if the WebVirtualHostService.start and WebConnectorService.start are firing at the same time.

Version-Release number of selected component (if applicable):


How reproducible:

Somewhat

Steps to Reproduce:
1. Enable byteman rule in JVM options:

-javaagent:/path/to/$BYTEMAN_HOME/lib/byteman.jar=script:/path/to/$BYTEMAN_HOME/01657328.btm,sys:/path/to/$BYTEMAN_HOME/lib/byteman.jar

2. Start up with the attached standalone xml and org.apache.catalina.connector.WAIT_FOR_BEFORE_START set:

./standalone.sh -c standalone-ha.xml -Dorg.apache.catalina.connector.WAIT_FOR_BEFORE_START=/foobar

3. Check for the exception.  Seeing this right before the forced StandardHost sleep is an indication that the problem start up ordering was hit:

16:07:50,528 INFO  [stdout] (MSC service thread 1-1) addContainerListener: StandardEngine[jboss.web].StandardHost[default-host] org.jboss.as.web.WebConnectorService$2@2749da2b


Actual results:

ClassCastException may occur

Expected results:

ClassCastException does not occur
