Andreas Pieber commented on PAXWICKET-25:
-----------------------------------------
I think I'm going to write a test case for this in "plain" wicket and in
pax-wicket. Let's see how they differ
> Cannot deserialize proxy classes
> --------------------------------
>
> Key: PAXWICKET-25
> URL: http://issues.ops4j.org/browse/PAXWICKET-25
> Project: Pax Wicket
> Issue Type: Bug
> Reporter: David Leangen
> Fix For: 1.0.0.RELEASE
>
>
> Proxy classes are not being serialized, which means that they cannot be
> deserialized.
> Upon deserialization by Wicket, an exception is thrown.
> Currently, this problem can be worked around by doing this:
> {code}
> public class SomeClass
> implements Serialziation
> {
> private static final long serialVersionUID = 1L;
> private transient Object someProxy;
> private final InvocationHandler handler;
> private final Class<?>[] proxyInterfaces;
> public SomeClass( Object someProxyInstance )
> {
> someProxy = someProxyInstance;
> final Class<?> someProxyClass = someProxy.getClass();
> if( Proxy.isProxyClass( someProxyClass ) )
> {
> handler = Proxy.getInvocationHandler( someProxy );
> proxyInterfaces = someProxyClass.getInterfaces();
> }
> else
> {
> handler = null;
> proxyInterfaces = null;
> }
> }
> private void writeObject( ObjectOutputStream out )
> throws IOException
> {
> out.defaultWriteObject();
> }
> private void readObject( ObjectInputStream in )
> throws IOException, ClassNotFoundException
> {
> in.defaultReadObject();
> if( null != m_handler && null != proxyInterfaces )
> {
> someProxy =
> (Object)Proxy.newProxyInstance(
> getClass().getClassLoader(),
> proxyInterfaces,
> handler );
> }
> }
> }
> {code}
> However, this is a really bad solution. The only real solution is to allow
> proxied classes to be properly serialized/deserialized like any other class.
