A method for runtime environment emulation comprising: loading an application class of an object-oriented application, wherein the object-oriented application is executing in a runtime environment, and wherein the application class comprises a method call that is unsupported by the runtime environment; and translating, during loading of the application class, the unsupported method call into at least one method call that is supported by the runtime environment, to obtain a translated class, wherein the at least one supported method call emulates the unsupported method call.
