The following test case fails when compiled in eclipse, but passes when compiled
with the Sun JDK.

Tested against integration build 3.1_I20050126-0800.

---- EnumTest.java ----

import junit.framework.TestCase;

public class EnumTest extends TestCase {
  /* 
   * MyEnum has a non-null, private constructor, and ITEM is an anonymous
   * subclass.  These three factors together cause a VerifyError to be thrown.
   * Omit any one factor and the test passes.
   */
  enum MyEnum {
    ITEM (0) {}; // curly braces make ITEM an anonymous subclass

    private MyEnum(int i) {}
  }

  public void testMyEnum() {
    try {
      MyEnum.values();
    } catch (VerifyError ve) {
      fail();
    }
  }

  /* 
   * MyEnumNoAnonymousSubclass has a non-null, private constructor.  No
   * VerifyError occurs.
   */
  enum MyEnumNoAnonymousSubclass {
    ITEM (0);

    private MyEnumNoAnonymousSubclass(int i) {}
  }

  public void testMyEnumNoAnonymousSubclass() {
    try {

    } catch (VerifyError ve) {
      fail();
    }
