JDK 16 introduced strong encapsulation of JDK internals (JEP 403), which prevents access to com.sun.tools.javac.* APIs used by Error Prone.
This results in IllegalAccessError during compilation.
To address this, we add --add-exports and --add-opens JVM flags to explicitly allow access to these internal APIs.
