* The vSphere cloud provider has a cleanup function with a loop,
    * inside of which a write lock was intended to prevent races against
    * VM creation, but the usage of the sync.RWMutex type is incorrect,
    * plus is placed in a defer call so the locking is effectively
    * nonexistent.  This patch adds an anonymous function call inside
    * the loop to correctly handle acquiring the write lock with deferred

    String string = sequence.toString();
    int pos = indexIn(string);
    if (pos == -1) {
      return string;
    }

    char[] chars = string.toCharArray();
    int spread = 1;

    // This unusual loop comes from extensive benchmarking
    OUT:
    while (true) {
      pos++;
      while (true) {
        if (pos == chars.length) {
          break OUT;
        }
        if (matches(chars[pos])) {

 *  Fix: Don't crash with a "cache is closed" error when there is an error initializing the cache.
 *  Fix: Calling `disconnect()` on a connecting `HttpUrlConnection` could cause it to retry in an
    infinite loop! This regression was introduced in OkHttp 2.7.0.
 *  Fix: Drop cookies that contain ASCII NULL and other bad characters. Previously such cookies
    would cause OkHttp to crash when they were included in a request.
