      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      Entity.java
      ========

      public abstract class Entity {
      public abstract String getName(String type);

      public final String getName() {
      return getName("DEFAULT");
      }
      }

      MyClass.java
      ==========

      public class MyClass<E extends Entity> {
      protected boolean test(E value, String name, String type) {
      return name.equals((type != null) ? value.getName(type) : value.getName());
      }
      }
      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Switch 'getName' methods like this:

      Entity.java
      ========

      public abstract class Entity {
      public final String getName() {
      return getName("DEFAULT");
      }

      public abstract String getName(String type);
      }
