Niall Pemberton commented on BEANUTILS-309:
-------------------------------------------

btw there is also the following invokeConstructor() method:
  public static Object invokeConstructor(Class, Object[], Class[])

..where you can specify the parameter types and avoid this issue. So in the example I gave above you would do the following to invoked the String constructor with a null argument:

ConstructorUtils.invokeConstructor(Foo.class, new Object[] {null}, new Class[] {String.class});

> Passing a null argument to ConstructorUtils.invokeConstructor causes NullPointerException

> I am invoking ConstructorUtils.invokeConstructor with an array of arguments and one of these arguments is null.
> This causes a NullPointerException line 120 in Class ConstructorUtils.
> Since its not forbidden to pass null argument to a constructor, ConstructorUtils should handle it.
