Java 8u20 を使用して、サンドボックス化されたアプレット内で次のことを行っています。
Set<Integer> set = new ConcurrentSkipListSet<Integer>();
set.add((int) 1);
そして、次の例外が発生します。

質問:
- この奇妙なアドレス "[0:0:0:0:0:0:0:1]:80" は何ですか?
- 回避策はありますか?
- このバグを Java に報告するにはどうすればよいですか、またはこれに関するバグレポートが既にありますか?
- 同様の同時実行動作を持つ ConcurrentSkipListSet に代わるものは何ですか?
- 多分：
Collections.newSetFromMap(new ConcurrentHashMap<Integer, Boolean>())？
