Java Applet Field Bytecode Verifier Cache Remote Code Execution

Description

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