Its definitely going through this line 493 in AbstractServerImpl:
log.info("JBoss (Microcontainer) [" +
jbossPackage.getImplementationVersion() + "] Started in " + watch);
but nothing is showing up in the console or ther server logs.
[509][valkyrie: log]$ grep 'JBoss (Microcontainer)' *.log
boot.log:10:11:46,427 INFO [ServerImpl] Starting JBoss (Microcontainer)...
[510][valkyrie: log]$
Something has to have changed with the log behavior.
