The counters are declared as Integer here: https://github.com/zsmartsystems/com.zsmartsystems.zigbee/blob/b15130c021219cbfe138dc4ec60423a0b8b3f679/com.zsmartsystems.zigbee.dongle.ember/src/main/java/com/zsmartsystems/zigbee/dongle/ember/ezsp/structure/EmberKeyStruct.java#L56 However, the specs says:    If I understand correctly, that may become an issue when the counters will reach high value, am I correct ? If yes, should we declare the properties as Long instead of Integer ?
