The code

    Deque<List<Object>> list = new LinkedList<List<Object>>();
    List<Object> lastRemoved = list.getLast();
    while (((Long) list.getFirst().get(0)).longValue() == ((Long) lastRemoved.get(0)).longValue()) {
        return;
    }
    throw new RuntimeException();

would be transformed into 

    Deque<List<Object>> list = new LinkedList<List<Object>>();
    List<Object> lastRemoved = list.getLast();
    while (((Long) list.getFirst().get(0)) == ((Long) lastRemoved.get(0))) {
        return;
    }
    throw new RuntimeException();

which causes the programmer to fix the comparison manually (i.e. add a `@SuppressWarning` in the case the comparison really should take place with `==` and `!=` or change the code.

This is especially annoying in conjunction with https://netbeans.org/bugzilla/show_bug.cgi?id=251078 because "Inspect and Transform" breaks your code and you won't even realize it.
