Subject Re: svn commit: r1210678 - in /commons/proper/digester/trunk/src: main/java/org/apache/commons/digester3/binder/ test/resources/org/apache/commons/digester3/xmlrules/
Date Tue, 06 Dec 2011 09:10:17 GMT
Hi Matt!!

indeed the commit contains too much informations here, I changed the
XML config just to see if the ClassLoader adapter is able to load
primitives by name, just moving the code you committed in the
ObjectCreate builder, so shared classloader across multiple binding is
able to provide the same feature.

I need to provide more specific testcase for that feature :P

Thanks for reviewing, really appreciated!

Simo
