Subject Re: Multiple Aliases Problem
Date Tue, 22 Nov 2011 07:17:31 GMT
Confirming that it is a bug. I filed an issue:
https://issues.apache.org/bugzilla/show_bug.cgi?id=52225


You would avoid this bug if you reorder your lines:
call "host.addAlias()" before you call "engine.addChild()".

That is what Digester does when parsing server.xml:
"engine.addChild()" method is called on the closing "</Host>" tag.

Best regards,
Konstantin Kolinko
