WICKET-6551 LazyInitProxyFactory doesn't work correctly at Weblogic
Try to load the class with the thread's context class loader and Wicket's
classes loader as a fallbacks

> LazyInitProxyFactory doesn't work correctly at Weblogic
> -------------------------------------------------------
>
> Key: WICKET-6551
> URL: https://issues.apache.org/jira/browse/WICKET-6551
> Project: Wicket
> Issue Type: Bug
> Components: wicket, wicket-spring
> Affects Versions: 6.21.0
> Reporter: Tomas Kloucek
> Assignee: Martin Grigorov
> Priority: Critical
>
> When weblogic serializes HTTP session then it's not an Wicket Application
> thread and Thread.currentThread().getClassLoader() can return different
> NOT-application classloader... which ends in
> LazyInitProxyFactory.readResolve() ClassNotFoundException crash...This ends
> in Wicket's WebSession being not saved into HTTP session which is fatal
> consequence....
> We have sucessfully tested following patch of LazyInitProxyFactory:
>
> {code:java}
> static class ProxyReplacement implements IClusterable
> {
> private static final long serialVersionUID = 1L;
> private final IProxyTargetLocator locator;
> private final String type;
> /**
> * Constructor
> *
> * @param type
> * @param locator
> */
> public ProxyReplacement(final String type, final IProxyTargetLocator
> locator) \{ this.type = type; this.locator = locator; }
> private Object readResolve() throws ObjectStreamException
> {
> Class<?> clazz = WicketObjects.resolveClass(type);
> if (clazz == null)
> {
> try
> { clazz = Class.forName(type, false, WicketObjects.class.getClassLoader());
> System.out.println("Clazz resolved through application classloade"); }
> catch (ClassNotFoundException e)
> { ClassNotFoundException cause = new ClassNotFoundException( "Could not
> resolve type [" + type + "] with the currently configured
> org.apache.wicket.application.IClassResolver"); throw new
> WicketRuntimeException(cause); }
> }
> return LazyInitProxyFactory.createProxy(clazz, locator);
> }
> }
> {code}
> With this patched LazyInitProxyFactory class problem went away. Can you
> please accomodate this fix into Wicket 6.x line?
