Processing engine for enabling a set of code intended for a first platform to be executed on a second platform

A non-transitory machine readable medium comprising instructions which, when executed by one or more processors, cause the one or more processors to implement a method for enabling a set of code intended to be executed on a first platform to be executed on a second platform, the second platform being different from the first platform, the method comprising:

• receiving the set of code, wherein the set of code is loaded for execution during runtime by a class loader, and wherein the processing engine is invoked when the class loader for loading the set of code is invoked;
• identifying a class in the set of code, the class comprising a non-static method call to a reflective method targeting a receiver object, wherein the non-static method call produces a different result when executed on the first platform as compared to being executed on the second platform;
• accessing a set of data that includes a first directive, the first directive specifying to replace the non-static method call with a method call to a substitute method configured to produce identical results to the reflective method;
• and
• rewriting, in accordance with the first directive, the set of code to replace the non-static method call with the method call to the substitute method, wherein the non-static method call is replaced by passing the receiver object to the substitute method in the method call, wherein the substitute method is configured to:
• identify, from a database, a set of methods comprising only methods that are exposed to the set of code when the set of code is executed in both the first platform and the second platform;
• and
• return the set of methods.
