SerializationUtils throws ClassNotFoundException when cloning of primitive classes
----------------------------------------------------------------------------------

                 Key: LANG-788
                 URL: https://issues.apache.org/jira/browse/LANG-788
             Project: Commons Lang
          Issue Type: Bug
    Affects Versions: 3.1
            Reporter: René Link


If a serializable object contains a reference to a primitive class, e.g. int.class or int[].class,
the SerializationUtils throw a ClassNotFoundException when trying to clone that object.

{noformat}
import org.apache.commons.lang3.SerializationUtils;
import org.junit.Test;


public class SerializationUtilsTest {

	
	@Test
	public void primitiveTypeClassSerialization(){
		Class<?> primitiveType = int.class;
		
		Class<?> clone = SerializationUtils.clone(primitiveType);
		assertEquals(primitiveType, clone);
	}
}
{noformat} 

The problem was already reported as a java bug http://bugs.sun.com/view_bug.do?bug_id=4171142
and ObjectInputStream is fixed since java version 1.4.
The SerializationUtils problem arises because the SerializationUtils internally use the ClassLoaderAwareObjectInputStream
that overrides the ObjectInputStream's
resoleClass method without delegating to the super method in case of a ClassNotFoundException.

I understand the intention of the ClassLoaderAwareObjectInputStream, but this implementation
should also implement a fallback to the original implementation.

For example:
{noformat}
        protected Class<?> resolveClass(ObjectStreamClass desc) throws IOException,
ClassNotFoundException {
            String name = desc.getName();
            try {
                return Class.forName(name, false, classLoader);
            } catch (ClassNotFoundException ex) {
            	try {
            	     return Class.forName(name, false, Thread.currentThread().getContextClassLoader());
            	} catch (Exception e) {
		     return super.resolveClass(desc);
		}
            }
        }
{noformat}
