1. Mail from Andy: javax.jdo.datastore.DataStoreCache - what to expect if a method is not supported > In DataStoreCache there are methods to pin and unpin objects in the cache. > When using this as an interface to the standard "javax.cache", there is no > feature to "pin" objects as such, and so DataNucleus does not implement these > methods. They simply throw UnsupportedOperationException. > > The question is, what should be the expected result? No-op? Exception, > meaning that it has to be handled in user code? > > No-op may be cleanest (particularly if the user is swapping between L2 cache > types to evaluate the best to use), but the javadoc doesn't define it, so > ought to be clarified in the spec/javadocs. The pin and unpin methods are hints, and there are no TCK tests for them. The implementation can ignore these hints. A valid implementation can implement the pin and unpin methods as no-op. No-op would seem to be a better implementation than throwing a runtime exception. If updating the javadoc would improve this situation, “someone" could file a JIRA and write a patch. The improvement might be as simple as adding javadoc to make it clear that these methods are only hints and cannot be tested. 2.
