You went to the trouble of checking test.src. Shouldn't CONFIG_FILE be found relative to SRC_DIR?
+ public static final Path SRC_DIR =
+ Paths.get(System.getProperty("test.src", "src"));
+ public static final Path USER_DIR =
+ Paths.get(System.getProperty("user.dir", "."));
+ public static final Path CONFIG_FILE = Paths.get("logging.properties");
