ABSTRACT:
A method for conditionally sharing dynamically compiled code between different class loaders is provided. In this method, bytecodes of a first class type are compiled into a compiled code if the bytecodes have not been compiled. The locations of sequence of instructions in the compiled code that are loader dependent are then recorded. Thereafter, the loader dependencies in the compiled code are compared to determine whether the compiled code can be used by a method of a second class type. If the loader dependencies of the second class type are different from the loader dependencies of the first class type, the compiled code for the method of the first class type is cloned. Subsequently, portions of the cloned code that are loader dependent are modified to enable the method of the second class type to use the cloned code.
