Abstract
A method and system for identifying calls in a Java package whose targets are guaranteed to belong to the package. According to the method an inheritance graph and access permissions of respective components in the package are determined, both of which are used in combination with the knowledge that the package is seared and signed to determine whether all the targets of a call are guaranteed to belong to the package. The identification of calls according to the invention can be performed at the time the package is sealed and signed or as a separate phase thereafter and allows for better compiler optimization.
