Abstract

Embodiments of the present invention disclose a method, system, and computer program product for a JNI object access system. A computer receives a JNI reference and obtains the pointer data and call site of the referenced object. The computer determines whether a record of the object and call site exist and, if not, the respective records are created. The computer applies a heuristic analysis of the object and call site in which it determines whether the object is larger than a threshold size, whether the object is part of a particular region of the heap, whether the call site is associated with a read-only or a read-write function, and whether the object or call site has caused more non-moving garbage collections than a threshold number. Based on the heuristic, the computer either copies the object data or pins the object and any non-moving garbage collections are recorded.
