I was playing with findbugs on jdk7
and it find a bug in sun.dyn.util.Wrapper
/** Return the wrapper that wraps values into the given wrapper type.
* If it is {...@code Object} or an interface, return {...@code OBJECT}.
* Otherwise, it must be a wrapper type.
* The type must not be a primitive type.
* @throws IllegalArgumentException for unexpected types
*/
public static Wrapper forWrapperType(Class<?> type) {
Wrapper w = findWrapperType(type);
if (w != null) return w;
for (Wrapper x : values())
if (w.wrapperType == type)
throw new InternalError(); // redo hash function
throw newIllegalArgumentException("not wrapper: "+type);
}
here
if (w.wrapperType == type)
should be
if (x.wrapperType == type)
