ATTENTION: This Exception does not provide a dedicated ConnectionAccessor as a DeviceComponent does not necessary provide dedicated connection information, it may be hard wired to another software system's hot spot or similar with the option of opening or closing. In order to provide compatibility with the Java APIs, this exception extends the IOException. E.g. JAVA APIs throw an IOException upon close, the Closable mixin throws an exception CloseException upon failure which can be assigned to an IOException reference (e.g. caught as an IOException).
