/**
 * @SneakyThrow will avoid javac's insistence that you either catch or throw onward any checked exceptions that
 * statements in your method body declare they generate.
 * 
 * @SneakyThrow does not silently swallow, wrap into RuntimeException, or otherwise modify any exceptions of the listed
 * checked exception types. The JVM does not check for the consistency of the checked exception system; javac does,
 * and this annotation lets you opt out of its mechanism.
 * 

 * Complete documentation is found at the project lombok features page for @SneakyThrows.
 * 

 * Example:
 * 
 * @SneakyThrows(UnsupportedEncodingException.class)
 * public String utf8ToString(byte[] bytes) {
 *     return new String(bytes, "UTF-8");
 * }
 * 
 * 
 * Becomes:
 *  * public String utf8ToString(byte[] bytes) {
 *     try {
 *         return new String(bytes, "UTF-8");
 *     } catch (UnsupportedEncodingException $uniqueName) {
 *         throw useMagicTrickeryToHideThisFromTheCompiler($uniqueName);
 *         // This trickery involves a bytecode transformer run automatically during the final stages of compilation;
 *         // there is no runtime dependency on lombok.
 *     }
 *
