> For performance reasons, ProtoStream changed the TypeId of WrappedMessage to 0, which means that pre 10.x clients using RemoteQuery are no longer compatible. Furthermore, ISPN-10663 updated the TypeId of the remote query messages to conform to the Infinispan TypeId ranges defined in ProtoStreamTypeIds.
> Therefore, for pre 10.x clients, it is neccessary for all remote query requests to have the legacy TypeId mapped to the new TypeId values. https://issues.jboss.org/browse/IPROTO-119 introduced a mechanism for this mapping, however more work is required, as the mapping must occur on a per request/response basis (only if communication is with a legacy client).
