ADDITIONAL SYSTEM INFORMATION :
My JDK is 21.0.1

A DESCRIPTION OF THE PROBLEM :
switch on enum value does not work if an enum-value overrides a method



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run test below

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
enum value should be properly recognized by switch-case.
ACTUAL -
default-branch is run instead of "B"

---------- BEGIN SOURCE ----------
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;

class SimpleTest {

  enum TestEnum {
    A, B {
      @Override
      public void foo() {
      }
    };

    public void foo(){
    }
  }

  @Test
  void test() {

    Assertions.assertEquals("B",
                            switch (TestEnum.B) {
                              case A -> "A";
                              case B -> "B";
                              case null -> "null";
                              default -> "default";
                            });
  }
}
