Summary: support for context classloader during deserialization

Initial Comment:

If OpenJMS is used in an Embedded system where the
classloaders are controlled through
Thread.currentThread().setContextClassloader(), it is
not able to properly deserialize object messages in
ObjectMessageImpl because it uses the default
implementation of ObjectInputStream.

Javadocs state that if you want to expand the
classloader capability, you need to extend the
resolveClass method yourself.

You would need to do something like the following:

protected Class resolveClass(ObjectStreamClass desc)
throws IOException, ClassNotFoundException {
ClassLoader cl =
Thread.currentThread().getContextClassLoader();
if (cl!=null)
return cl.loadClass(desc.getName());
return super.resolveClass(desc);
}
