secureCodeBox#121 Remove Checked Exception to Provide a Cleaner API

Checked exceptions in a public used API is quite cumbersome. Alo checked exceptions should onlybe used forerrors you can deal with in the source code. Since the errors in this case origin from outside, it is better to use runtime exceptions. This does not clutter the API clients. Signed-off-by: Sven Strittmatter <[email protected]>
