| DataNucleus compatibility matrixBecause Cumulus4j is a plug-in to DataNucleus, both products must be compatible in order to cooperate. Not every version of Cumulus4j can be used with every version of DataNucleus. Therefore, we test Cumulus4j with a few versions of datanucleus-core and datanucleus-rdbms before every release. 
				If all our tests
				run successfully, we assume Cumulus4j and DataNucleus
				to be fully compatible and indicate it in the following table by this
				symbol:
				 
				If Cumulus4j works with DataNucleus, but not all tests succeed (i.e.
				at least one test fails) or if there is
				any other irregularity, we indicate this by a warning symbol:
				 
				If a certain version of Cumulus4j cannot be used at all with a
				certain version of DataNucleus, it is indicated
				by this symbol:
