MethodHandles.Lookup.findVirtual() Javadoc fails to consider private interface methods

    Details

      Description

      MethodHandles.Lookup.findVirtual() throws IllegalAccessException if the method MH is being created for is private and declared in an interface.

      Example:
      import java.lang.invoke.MethodHandles;
      import java.lang.invoke.MethodType;

      public interface PrivateInterfaceMethodLookupTest {
          public static void main(String[] args) throws NoSuchMethodException, IllegalAccessException {
              MethodHandles.lookup()
                      .findVirtual(PrivateInterfaceMethodLookupTest.class, "m", MethodType.methodType(void.class));
          }

          private void m() {}
      }

      Output:
      Exception in thread "main" java.lang.IllegalAccessException: no such method: PrivateInterfaceMethodLookupTest.m()void/invokeInterface
