>       if (!removedProxy) {
>         // all of the proxies are currently in use and already scheduled
>         // for removal, so we need to wait until at least one of them closes
>         try {
>           this.wait();
> {code}
> The above code can wait for a condition that has already been satisfied, leading to indefinite
wait.
