[jira] [Updated] (LANG-788) SerializationUtils throws
ClassNotFoundException when cloning primitive classes
[ https://issues.apache.org/jira/browse/LANG-788?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
René Link updated LANG-788:
---------------------------
Summary: SerializationUtils throws ClassNotFoundException when cloning primitive classes (was: SerializationUtils throws ClassNotFoundException when cloning of primitive classes)
> 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
>
> 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}
