Abstract

See full text

A computer-implemented method includes receiving an invocation of an invoked interface associated with a class, identifying, based on the class, a plurality of interface lookup artifacts and a cached interface lookup artifact, and comparing the invoked interface with a cache interface. The cache interface is associated with the cached interface artifact. The computer-implemented method further includes, responsive to the invoked interface matching the cache interface, returning the cached interface artifact, and responsive to the invoked interface not matching the cache interface, searching the plurality of interface lookup artifacts until finding a matching interface lookup artifact. The matching interface lookup artifact is associated with a matching interface that matches the invoked interface. Responsive to finding the matching interface lookup artifact, returning the matching interface lookup artifact and updating the cached interface lookup artifact to the matching interface lookup artifact. A corresponding computer program product and computer system are also disclosed.
