JetBrains [is working on][kotlin_sams] SAM conversions of Kotlin interfaces. Expect it in a future
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

    /**
     * Returns {@code true} if there is at least one problem collected with severity equal or more severe than
     * {@link org.apache.maven.api.services.BuilderProblem.Severity#WARNING}. This check is logically equivalent
     * to "is there any problem reported?", given warning is the lowest severity.
     */
    default boolean hasWarningProblems() {
        return hasProblemsFor(BuilderProblem.Severity.WARNING);
    }

    /**

}

var errorRune = []byte(string(utf8.RuneError))

// ScanRunes is a split function for a [Scanner] that returns each
// UTF-8-encoded rune as a token. The sequence of runes returned is
// equivalent to that from a range loop over the input as a string, which
// means that erroneous UTF-8 encodings translate to U+FFFD = "\xef\xbf\xbd".
// Because of the Scan interface, this makes it impossible for the client to

        }
        return value;
    }

    /**
     * Escapes special characters in a query string if escaping is enabled.
     * Replaces reserved characters with their escaped equivalents based on the Constants.RESERVED array.
     *
     * @param value the query string to escape
     * @return the escaped query string, or the original value if escaping is disabled
     */

     * or
     * proto:server[key1=val1,key2=val2]
     * or
     * proto:[key1=val1,key2=val2]
     *
     * If a key is absent it is assumed to be 'endpoint'. Thus the
     * following are equivalent:
     * proto:\\ts0.win.net[endpoint=\pipe\srvsvc]
     * proto:ts0.win.net[\pipe\srvsvc]
     *
     * If the server is absent it is set to "127.0.0.1"
     */
    /**

  }

  /**

   * contains any match for the given regular expression pattern. The test used is equivalent to

   * @throws IllegalArgumentException if the pattern is invalid

            throw new IllegalStateException("Authenticator has been closed");
        }
    }

    /**

     * <code>domain\\username</code>. This is equivalent to <code>toString()</code>.

    @Override
    public String getName() {
        boolean d = this.domain != null && this.domain.length() > 0;
