Description
http://mail.openjdk.java.net/pipermail/mlvm-dev/2012-March/004398.html

This snippet creates an infinite loop :(

        java.lang.ClassValue<Integer> cv = new 
java.lang.ClassValue<Integer>() {
             @Override
             protected Integer computeValue(Class<?> type) {
                 remove(int.class);
                 return 1;
             }
         };
         cv.get(int.class);
