> The JcrPropertyMap and JcrModifiablePropertyMap only support reading and writing the object types supported by JCR. It is currently not possible to store any serializable objects.
> Supporting the writing of serializable objects is easy, we just have to enhance the JcrModifiablePropertyMap to write the serialized object into the repository (through an ObjectOutputStream).
> Reading a serialized object is more tricky as the implementation does not know in advance, if the input stream contains a serialized object or some arbitrary data.
> The check for this is a little bit expensive as it would require to first try to read the data through an ObjectInputStream and if that success we have the serialized object. If this is not successful, a new input stream has to be used.
> As I think that this is a very valuable feature (for example the Sling eventing has a use case for this), we should do this special check only under certain circumstances, for example
> a) if ValueMap.get(KEY) is invoked and  the property is an input stream
> or
> b) if ValueMap.get(KEY, Object.class) is used
> Any other ideas, suggestions?
