  • Systems, methods, and computer products for automated injection of java bytecode instructions for java load time optimization via runtime checking with upcasts
    Patent number: 8161470
    Abstract: Automated injection of Java bytecode instructions for Java load time optimization via runtime checking with upcasts. Exemplary embodiments include a method including generating a stack for each of a plurality of bytecodes, generating a subclass configured to keep a history of instructions that have modified the stack, statically scanning a plurality of Java classes associated with the plurality of bytecodes to locate class file configurations and bytecode patterns that cause loading of additional classes to complete a verification of each of the classes in the plurality of Java classes, rewriting the bytecodes to delay the loading of the additional classes until required at a runtime, recording modifications that have been made to the stack by the instructions, and applying the modifications to each of the bytecodes in the plurality of bytecodes.
