> The exception handling in this utility class is unclear and can in some cases cause ClassCastException to be thrown.
> Note that SecurityException is a runtime exception.
> Potential issues to be fixed:
>  1) Avoid possibility of ClassCastException in 'getFileInputStream'
>  2) Don't include SecurityException in the signature (throws clause)
>  3) Document SecurityException in JavaDoc.
> Points 2 and 3 leads to the option of not catching SecurityException, which allows the code to be written more concisely and we can use PrivilegedAction instead of PrivilegedExceptionAction in some cases.
> There is also a missing character in the class name in the header, and an invalid JavaDoc tag in the class JavaDoc.
