------------------------------------------------------------------- private static final Object handleRestoreState(FacesContext context, Object state) { if (ContextInitParameters.isSerializeServerState(context)) { ObjectInputStream ois = null; try { ois = new ObjectInputStream(new ByteArrayInputStream((byte[]) state)) { @Override protected Class<?> resolveClass(ObjectStreamClass desc) throws IOException, ClassNotFoundException { return Class.forName(desc.getName(), true, Thread.currentThread().getContextClassLoader()); } }; return ois.readObject(); } catch (Exception e) { throw new FacesException(e); } finally { if (ois != null) { try { ois.close(); } catch (IOException ignored) { } } } } else { return state; } } From the debug: ObjectStreamClass is boolean: static final long serialVersionUID = 0L; before the exception occured. I could not figure out where the type "boolean" came from. Data can be serialized, but it can not be deserialized back.
