--------------------------------------
Committed and added missing support to the patch for {{void.class}}
> SerializationUtils throws ClassNotFoundException when cloning 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
> Fix For: 3.2

> Attachments: LANG-788

>
> 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}
> Here is the code in ObjectInputStream that fixed the java bug.
> {noformat}
> protected Class<?> resolveClass(ObjectStreamClass desc)
> throws IOException, ClassNotFoundException
> {
> String name = desc.getName();
> try {
> return Class.forName(name, false, latestUserDefinedLoader());
> } catch (ClassNotFoundException ex) {
> Class cl = (Class) primClasses.get(name);
> if (cl != null) {
> return cl;
> } else {
> throw ex;
> }
> }
> }
> {noformat}
