IllegalAccessException while instrumenting invocation of non-public method with RuntimeHintsAgent

[bclozel]

The RuntimeHintsAgent agent fails at instrumenting the following case:

@EnabledIfRuntimeHintsAgent
class RuntimeHintsAgentTests {

	@Test
	void invokePrivateMethod() {
		Method greet = ReflectionUtils.findMethod(PrivateClass.class, "greet");
		RuntimeHintsInvocations invocations = RuntimeHintsRecorder.record(() -> {
			greet.invoke(new PrivateClass());
		});
	}

	class MyClass {

		private String greet() {
			return "hello";
		}
		
	}
}

With this code snippet, the agent fails during the method invocation with an exception like:

java.lang.IllegalAccessException: class org.springframework.aot.agent.InstrumentedBridgeMethods cannot access a member of class org.springframework.sample.RuntimeHintsAgentTests$MyClass with modifiers "private"

Reopening for cases where methods are public but declaring class is not.
