Benedikt Ritter resolved SANDBOX-441.
-------------------------------------
Resolution: Fixed
I added checks for instantiability invokeConstructor(). I also changed
newInstance() to delegate to the private invokeConstructor() method with no
arguments. This way we can be sure that every call to a constructor will be
checked. Committed in r1445335.

> The handling of InstantiationException could be improved to give users a
> better feedback of what went wrong (see JavaDoc of Class<T>.newInstance() for
> reasons why instantiation may fail):
> * check if a default constructor is available and throw
> NoSuchConstructorException if not
> * else throw BeanInstantiationException but inspect beanType in
> BeanInstantiationException and set specific messages for the following cases:
> ** BeanType is abstract
> ** BeanType is an interface
> ** BeanType is a primitive type
> ** BeanType is an array type
> ** BeanType represents void
> ** if none of the above use a generic message
