Potentially unsafe implementations of method-based entrypoints

See original GitHub issue

The current language adapter creates an entrypoint from methods with proxies. However, the invocation handler delegates all calls, meaning if the entrypoint created was called with e.g. hashCode (such as adding to a hash set) something wrong may happen. In addition, default methods from entrypoint interfaces are broken as well.

I have looked into using lambdas, but it appears that lambdas need tricky access and cannot be used properly after the introduction of hidden classes (cannot obtain lookups easily).

Guess a better solution for this is that we write our own asm class generator in the future.

Yeah, the plan a while ago is to create a java 16 component like a loader plugin to support those advanced functionalities.
