From 4d0c5fe67aab45007ca0c41a9c6bc462cb04dd96 Mon Sep 17 00:00:00 2001 From: Sven Strittmatter Date: Fri, 16 Feb 2024 16:14:08 +0100 Subject: [PATCH] #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.
