Because 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:
