The following paragraph should be added to the doc for java.lang.Class.newInstance:

Note that this method propagates any exception thrown by the nullary constructor, including a checked exception. Use of this method effectively bypasses the compile-time exception checking that would otherwise be performed by the compiler. The {@link java.lang.reflect.Constructor#newInstance(java.lang.Object...)} method avoids this problem by wrapping any exception thrown by the constructor in a (checked) {@link java.lang.reflect.InvocationTargetException}.
