A bug in org.apache.cocoon.classloader.DefaultClassLoader
---------------------------------------------------------
Key: COCOON-1921
URL: http://issues.apache.org/jira/browse/COCOON-1921
Project: Cocoon
Issue Type: Bug
Components: * Cocoon Core
Affects Versions: 2.2-dev (Current SVN)
Reporter: Rice Yeh
On the implementation of loadClass(String name, boolean resolve) in
DefaultClassLoader , when there is no class found in child (that is, this
classloader) classloader, the parent's loadClass() method is called. However,
on present implementation it is parent.loadClass(name) called, which is the
java.lang.ClassLoader's loadClass() called and it uses parent-first loading
strategy. In order to use child-first strategy (if the parent is also a
DefaultClassLoader), the following patch should be applied:
