Krzysztof Nienartowicz commented on OPENJPA-2402:
-------------------------------------------------
In our case DataCache is never used (regardless the FetchMode) when a map is
used in way like this:
@OneToMany(mappedBy = "fParent", cascade =
{CascadeType.PERSIST,CascadeType.MERGE,CascadeType.REFRESH},
fetch = FetchType.EAGER)
@EagerFetchMode(FetchMode.PARALLEL) // does not change behaviour
@MapKey(name = "fTsType")
@ElementType(TsImpl.class)
@ReadOnly(UpdateAction.IGNORE)
protected Map<TsType, Ts> fTS = new HashMap<TsType, Ts>();
We populate the cache with the native query (seen in the log) but i.e.
DelegatingDataCache get methods are never called when accessing fTS.
openjpa 2.3.0
