Adrian Nistor commented on ISPN-3571:
-------------------------------------

[~mgencur] It seems this is not a bug in protostream. The actual problem is the selection of the query facade implementation. In your case the order of dependencies lead to the selection of DummyQueryFacade instead of QueryFacadeImpl, which really cannot work. I've fixed the order of dependencies in my branch here: https://github.com/anistor/infinispan/commit/5d660960e5f07a107d7e5966d9e8f96dae868542
