 * <p>If no backing thread factory is provided, a default backing thread factory is used as if by
 * calling {@code setThreadFactory(}{@link Executors#defaultThreadFactory()}{@code )}.
 *
 * <p><b>Java 21+ users:</b> consider using the {@code Thread.Builder} interface instead. E.g.,

            thread.setUncaughtExceptionHandler(UNCAUGHT_EXCEPTION_HANDLER);
            return thread;
          }
        };

    Thread thread =
        builder.setThreadFactory(backingThreadFactory).build().newThread(monitoredRunnable);

    assertEquals(THREAD_NAME, thread.getName());
    assertEquals(THREAD_PRIORITY, thread.getPriority());
    assertEquals(THREAD_DAEMON, thread.isDaemon());

            thread.setUncaughtExceptionHandler(UNCAUGHT_EXCEPTION_HANDLER);
            return thread;
          }
        };

    Thread thread =
        builder.setThreadFactory(backingThreadFactory).build().newThread(monitoredRunnable);

    assertEquals(THREAD_NAME, thread.getName());
    assertEquals(THREAD_PRIORITY, thread.getPriority());
    assertEquals(THREAD_DAEMON, thread.isDaemon());
