    Description

      from http://forum.java.sun.com/thread.jsp?forum=316&thread=523496

      I have changed the code to make it compile:

      abstract class Test {

          protected <T> void getConstructor(Class<? extends T> clazz) {
              Class<? extends T> impl;
              impl = clazz.isInterface() ? getImplementationClass(clazz) : clazz;
              if (clazz.isInterface()) {
                  impl = getImplementationClass(clazz);
              } else {
                  impl = clazz;
              }
          }


          abstract public <T> Class<? extends T>
          getImplementationClass(Class<T> interfaceClass);
      }

      This line don't compile in tiger-fcs, but compiled in b48:

      impl = clazz.isInterface() ? getImplementationClass(clazz) : clazz;
