Java Applet Field Bytecode Verifier Cache Remote Code Execution

This module exploits a vulnerability in HotSpot bytecode verifier where an invalid optimisation of GETFIELD/PUTFIELD/GETSTATIC/PUTSTATIC instructions leads to insufficent type checks. This allows a way to escape the JRE sandbox, and load additional classes in order to perform malicious operations.
