the compiler, e.g. suppressing type-checking, raw generics, and so on. However,
this isn't always possible or practical. In such cases, you should use the
`@SuppressWarnings` annotations to silence the compiler warning, trying to keep
the scope of the suppression as small as possible. Where a piece of code
requires a lot of suppressions, it may be better to apply a single suppression

### Container Images

All container images are available as manifest lists and support the described
architectures. It is also possible to pull a specific architecture directly by
adding the "-$ARCH" suffix  to the container image name.

name | architectures
---- | -------------

    "ThreadPriorityCheck", // TODO: b/175898629 - Consider onSpinWait.
  })
  private void waitForInterrupt(Thread currentThread) {
    /*
     * If someone called cancel(true), it is possible that the interrupted bit hasn't been set yet.
     * Wait for the interrupting thread to set DONE. (See interruptTask().) We want to wait so that
     * the interrupting thread doesn't interrupt the _next_ thing to run on this thread.

    return this;
  }

  /**
   * Returns a new thread factory using the options supplied during the building process. After
   * building, it is still possible to change the options used to build the ThreadFactory and/or
   * build again. State is not shared amongst built instances.
   *
   * <p><b>Java 21+ users:</b> use {@link Thread.Builder#factory()} instead.
   *

You can also use `File()` with `UploadFile`, for example, to set additional metadata:

{* ../../docs_src/request_files/tutorial001_03_an_py310.py hl[9,15] *}

## Multiple File Uploads { #multiple-file-uploads }

It's possible to upload several files at the same time.

They would be associated to the same "form field" sent using "form data".

To use that, declare a list of `bytes` or `UploadFile`:

    .build();
```

Client Authentication
---------------------

The above scenario is representative of most TLS set ups: the client uses certificates to validate
the identity of a server. The converse is also possible. Here we create a server that authenticates
a client and a client that authenticates a server.

```java
// Create the root for client and server to trust. We could also use different roots for each!

   * Returns {@code table[index]}, where {@code table} is actually a {@code byte[]}, {@code
   * short[]}, or {@code int[]}. When it is a {@code byte[]} or {@code short[]}, the returned value
   * is unsigned, so the range of possible returned values is 0–255 or 0–65535, respectively.
   */
  static int tableGet(Object table, int index) {
    if (table instanceof byte[]) {
      return ((byte[]) table)[index] & BYTE_MASK; // unsigned read
