Abstract
A computer implemented method, data processing system, and computer program product for automatic discovery of the Java classloader delegation hierarchy. One or more classloaders are instrumented with byte code instrumentation code such that a delegation event is received each time a classloader delegates a resource finding method to a parent classloader of the classloader. From each delegation event received, the classloader that generated the delegation event and a parent classloader to which the classloader directly delegates the resource finding method is determined. Based on the delegation events received, the classloaders to which a current classloader in the one or more classloaders can directly delegate are determined. The order of delegation to the classloaders may then be determined.
