Abstract: A method for obtaining accurate call path information in a mixed-mode environment where interpreted methods and non-interpreted methods can call one another is disclosed. In one embodiment, such a method includes generating an event and recording it in a buffer when an interpreted method calls an interpreted method. The method also generates an event and records it in the buffer when an interpreted method calls a non-interpreted method. The method further generates an event and records it in the buffer when a non-interpreted method calls an interpreted method. The method refrains from generating an event when a non-interpreted method calls a non-interpreted method. A corresponding apparatus and computer program product are also disclosed.

Abstract: An illustrative embodiment for serialization of pre-initialized objects receives a source code definition of a class, identifies a set of constants associated with the class in the source code to form a set of identified constants, creates a result object corresponding to each constant in the set of identified constants, and compiles the source code into a compiled form of the class. The illustrative embodiment further serializes each result object into a resource file associated with the class to form a set of serialized objects and replaces, in the compiled form of the class, each reference to a respective constant associated with the class from the set of identified constants with a corresponding dynamic instruction using a respective serialized object in the set of serialized objects.

Abstract: At least one literal value data structure within a literal pool data structure that is capable of being resolved by run-time initialization within a virtual runtime environment is defined by a processor within a memory storage area. A run-time reference to one of the at least one literal value data structure within the literal pool data structure is detected. A determination is made as to whether a literal value at the one of the at least one literal value data structure is resolved and run-time accessible. The literal value at the one of the at least one literal value data structure within the literal pool data structure is resolved during run-time in response to determining that the literal value is not resolved. The resolved literal value is returned.
