Subject svn commit: r925961 - /commons/proper/lang/trunk/src/main/java/org/apache/commons/lang3/reflect/MethodUtils.java
Date Mon, 22 Mar 2010 05:59:31 GMT
Author: bayard
Date: Mon Mar 22 05:59:31 2010
New Revision: 925961

URL: http://svn.apache.org/viewvc?rev=925961&view=rev
Log:
Moving most of the methods over to varargs. A couple can't change because they are Object[],
Class[] with both end parameters ideally wanting to be vararg. LANG-396
