Problem with check config on DBJoin

this is not a graph stopping error, but when check config is called on a DBJoin node it uses a DBLookupTable and in the graph output after “initializing nodes:” it says

WARN [WatchDog] - Graph element [LOOKUP_TABLE_FROM_spbpersAddSourceFields] is not checked by checkConfig() method. Please call TransformationGraph.checkConfig() first.

This warning is because new lookup table is created in init() method and lookupTable.checkConfig(null) is not called. In new release this will be called, so there will be no warning on output.
