We used to treat requests to get a store with a null name as implicitly meaning get the default named store. But a recent change (JBTM-2207 Make default name null in order for quick lookup) meant that this is no longer the default behaviour. Now a request like the following

BeanPopulator.getNamedInstance(ObjectStoreEnvironmentBean.class, null);

will return something other than the default named instance. This is causing a problem on wildfly where the call StoreManager.getRecoveryStore() does not return what was set in the transaction subsystem service initialisation.

The fix is to explicitly set the name, ie replace calls like

BeanPopulator.getNamedInstance(ObjectStoreEnvironmentBean.class, null);

with

BeanPopulator.getNamedInstance(ObjectStoreEnvironmentBean.class, "default");
