Jetty has a class named TypeUtil, see here. In this class, they use MethodHandles.Lookup to get MethodHandles to getCodeSourceLocation, etc.

When running a test which uses the TypeUtil with agent attached, I can see getCodeSourceLocation etc, but the signature is wrong:

{ "condition":{"typeReachable":"org.eclipse.jetty.util.TypeUtil"}, "name":"org.eclipse.jetty.util.TypeUtil", "methods":[ {"name":"getClassLoaderLocation","parameterTypes":[] }, {"name":"getCodeSourceLocation","parameterTypes":[] }, {"name":"getModuleLocation","parameterTypes":[] }, {"name":"getSystemClassLoaderLocation","parameterTypes":[] } ] }

The signatures are URI as return type and Class<?> as only argument, e.g. public static URI getCodeSourceLocation(Class<?> clazz)
