A method, system, and apparatus for minimizing run-time exception handling overhead from invoked function calls. The present invention novelly minimizes execution of exception checking code and exception handling code in a caller when the callee is a compiled method. In the present embodiment the callee novelly treats the caller as a compiled method thereby enabling the callee to return to the exception handling label of the caller if an exception needs to be handled and to return and continue normal code execution if an exception does not need to be handled. Thereby the present invention minimizes execution of exception handling code in the caller. Further, the present embodiment novelly creates code with the layout of a compiled method when a caller is not a compiled method so that a compiled callee may treat its caller as a compiled method.

A conversation definition language (CDL) is disclosed that programmers may use to define sequences of interactions for communicating with a web service to facilitate use of the web service. CDL enables web services provided by different entities to engage in flexible and autonomous interactions. Using CDL, services can communicate by exchanging messages, and the message exchanges are expected to follow a specific pattern (i.e., a conversation). CDL is used to define the conversation, such that a service may expect a particular message in response to transmitting a particular message. CDL includes document type descriptions, interactions and transitions for describing a conversation. The document type descriptions describe the messages that may be exchanged. The interactions describe the type of actions (e.g., receive and/or transmit a message) that may be performed, and the transitions describe the possible sequences of the interactions.

A method and system for increasing security of a software program by obfuscation of program execution flow is disclosed, wherein the software program is executed on a computer system that includes a user-level protected mode and a kernel-level unprotected mode. The method and system include first identifying critical code segments to be hidden in the software program. The non-critical portions of the software program are then executed in the user-level protected mode, while the critical code segments are executed within respective exception handlers, thereby hiding execution of the critical code segments from a debugger program.

A method and a device for handling errors of software modules for redundantly designed systems in vehicles in order to optimize error handling for redundantly designed systems in vehicles, so that errors are detected and error handling measures are introduced. In addition, error handling is configured in such a way that it can be used for a plurality of software-controlled applications that run on a control device. Furthermore, a device for performing the method uses direct and/or indirect redundant input data to determine the adjusted input data for the software modules.

The present invention method and system ensure execution of post processing logic for a subject computer program routine (e.g., JAVA application) without wrapping the routine inside another. The invention system and method include different sets of exit handling steps for different types of exits in the subject routine. In each set of exit handling steps, the post processing logic is executed. Flow of control of the subject routine resumes at the respective exit point.
