A system and method are disclosed for improving the performance of compiled Java code. Java source code is annotated and then compiled by a Java compiler to produce annotated Java bytecode, which in turn is compiled by a just-in-time (JIT) compiler into annotated native code. The execution of the annotated native code is monitored with a patching agent, which captures the annotated native code as it is being executed. The captured native code is then provided through an application program interface to a dynamic linkage module, which in turn provides the captured native code to a user or to an application plug-in module for modifications. The modifications are saved as a patch. The annotated native code is then re-executed and the modifications to the annotated native code are applied as a patch by the patching agent.
