Abstract
A data processing system and method manage the storage of instructions used in applications developed using an interpretive programming language, such as Java, REXX, BASIC, and the like, when those instructions are compiled into byte-codes to be used by a virtual machine stored in a 'heap.' In the data processing system and method, an exception is registered in a page manager of an operating system to identify that compiled code should be stored within the heap of the virtual machine. After that code has been compiled and deleted from the heap, an exception occurs when the virtual machine attempts to subsequently access the compiled code. At that point, the virtual machine is then enabled to retrieve the desired code from an interpreted programming language application.
