release of the Kotlin language.


Companion Imports
-----------------

The equivalent of static methods in Java is companion object functions in Kotlin. The bytecode is
the same but `.kt` files now need `Companion` in the import.

This works with OkHttp 3.x:

```kotlin

@JvmField
internal val EMPTY_REQUEST: RequestBody = commonEmptyRequestBody

@JvmField
internal val EMPTY_RESPONSE: ResponseBody = commonEmptyResponse

/** GMT and UTC are equivalent for our purposes. */
@JvmField
internal val UTC: TimeZone = TimeZone.getTimeZone("GMT")!!

internal fun threadFactory(
  name: String,
  daemon: Boolean,
): ThreadFactory =
  ThreadFactory { runnable ->

      return toStringHelper(this)
          .add("aString", aString)
          .add("anInt", anInt)
          .add("anEnum", anEnum)
          .toString();
    }
  }

  /** Validates that the Comparator equivalent we document is correct. */
  @J2ktIncompatible // TODO b/315311435 - J2kt cannot emulate Comparator<C>.<U>thenComparing()
  public void testComparatorEquivalent() {
    Comparator<Foo> comparatorUsingComparisonChain =

@echo off
@REM set title of command window
title %0
@REM enable echoing by setting MAVEN_BATCH_ECHO to 'on'
@if "%MAVEN_BATCH_ECHO%" == "on"  echo %MAVEN_BATCH_ECHO%

@REM set %HOME% to equivalent of $HOME
if "%HOME%" == "" (set "HOME=%HOMEDRIVE%%HOMEPATH%")

@REM Execute a user defined script before this one
if not "%MAVEN_SKIP_RC%" == "" goto skipRcPre

## Singular values in body

The same way there is a `Query` and `Path` to define extra data for query and path parameters, **FastAPI** provides an equivalent `Body`.

For example, extending the previous model, you could decide that you want to have another key `importance` in the same body, besides the `item` and `user`.

        ComparableVersion c1 = new ComparableVersion("1");
        c1.parseVersion("2");

        Comparable<?> c2 = newComparable("2");

        assertEquals(c1, c2, "reused instance should be equivalent to new instance");
    }

    /**
     * Test <a href="https://issues.apache.org/jira/browse/MNG-7644">MNG-7644</a> edge cases

  public static ByteSource asByteSource(Path path, OpenOption... options) {
    return new PathByteSource(path, options);
  }

  public static ByteSource asByteSource(Path path, OpenOption... options) {
