But allocating/deallocating and even dereferencing a jni handle involve first performing a vm state transition which will perform a safe point check. Local jni handles are auto managed so when the code returns from a jni method that is it transitions from state native doing a safe point check ...

In a JSON Schema document it is possible to use relative URIs to refer previously defined types. Such references are expressed using the"$ref"and"$id"keywords. While the specification describes resolution scope alteration and dereferencing in detail, it doesn't explain the expected behavior when ...
Another design makes an object reference a native pointer to a bundle of data that contains the object's instance data and a pointer to the object's class data. This approach requires dereferencing only one pointer to access an object's instance data, but makes moving objects more complicated...
( )).Once one of the mutator methods has been called, theWeakHashMapruns through itsReferenceQueue, removing allWeakReferenceobjects from the queue and also removing eachWeakReferenceobject as a key in its internal map, thus simultaneously dereferencing the value.
