MissingMethodInvocationException is thrown when mocking native method in 5.x

[franzwong]

• The mockito message in the stacktrace have useful information, but it didn't help
• The problematic code (if that's possible) is copied here;
  Note that some configuration are impossible to mock via Mockito
• Provide versions (mockito / jdk / os / any other relevant information)
• Provide a Short, Self Contained, Correct (Compilable), Example of the issue
  (same as any question on stackoverflow.com)
• Read the contributing guide

Problematic version: 5.0.0, 5.10.0
JDK: 17
OS: MacOS

The following piece of code was fine with 4.x (I tried with 4.11.0). However, it throws exception after upgrading to 5.x. I think that's because the totalMemory method is native. However, the exception message doesn't mention that.

public class FooTest {
    @Test
    public void fooTest() {
        var runtime = mock(Runtime.class);
        when(runtime.totalMemory()).thenReturn(1000L);
    }
}

Exception message:

org.mockito.exceptions.misusing.MissingMethodInvocationException: 
when() requires an argument which has to be 'a method call on a mock'.
For example:
    when(mock.getArticles()).thenReturn(articles);

Also, this error might show up because:
1. you stub either of: final/private/equals()/hashCode() methods.
   Those methods *cannot* be stubbed/verified.
   Mocking methods declared on non-public parent classes is not supported.
2. inside when() you don't call method on mock but on some other object.

A PR that updates the message to list final/private/native/equals()/hashCode() would be welcome!
