Title: Message Title

Tobias Gierke created an issue   XStream / XSTR-767 Serializing lambda expressions fails with XStream and JDK 1.8u40 Issue Type: Bug Affects Versions: 1.4.7 Assignee: Jörg Schaible Components: Core Created: 07/Jan/15 3:04 AM Priority: Major Reporter: Tobias Gierke It seems we're not able to deserialize Lambda expressions with XStream 1.4.7 The code in question looks roughly like this: @FunctionalInterface public interface Visible extends Serializable { public boolean isVisible(); } public interface IMenuItem extends Serializable { // ... stuff omitted ... } public abstract class AbstractMenuItem implements IMenuItem { private final Visible visibilityFunction; // ... stuff omitted ... } The method that is invoked with lambda expressions (that later get stored in the 'visibilityFunction' field of an AbstractMenuItem subclass instance) looks like this: public <T extends Page> void addEntry(String resourceLabel , Class<T> pageClazz,Visible visibilityFunction); Since the Visible interface extends Serializable , the compiler generates code for a serializable Lambda (and in fact it does, I checked the generated .class file with javap). The code used to setup XStream looks like this: private XStream createXStream() { final XStream xstream = new XStream( new StaxDriver() ) { @Override protected MapperWrapper wrapMapper(MapperWrapper next) { return new WicketProxyMapper( new CGLIBMapper( new HibernateMapper(next) ) ); // } }; // override the built-in DynamicProxyConverter that chokes on Apache Wicket proxies xstream.registerConverter( new WicketProxyConverter() , XStream.PRIORITY_VERY_HIGH ); // register Hibernate-specific converters xstream.registerConverter(new HibernateProxyConverter()); xstream.registerConverter(new HibernatePersistentCollectionConverter(xstream.getMapper())); xstream.registerConverter(new HibernatePersistentMapConverter(xstream.getMapper())); xstream.registerConverter(new HibernatePersistentSortedMapConverter(xstream.getMapper())); xstream.registerConverter(new HibernatePersistentSortedSetConverter(xstream.getMapper())); // register CGLLib converters xstream.registerConverter(new CGLIBEnhancedConverter(xstream.getMapper(), xstream.getReflectionProvider() , getClass().getClassLoader() ) ); return xstream; } Add Comment   This message was sent by Atlassian JIRA (v6.1.6#6162-sha1:7af547c) To unsubscribe from this list please visit: http://xircles.codehaus.org/manage_email
