2chビューで板を選択すると、NullPointerExceptionが
生じる。その後、スレッドビューでツリーを展開すると
1..50とか51...100のツリー開いても先頭の1とか51しか出ない。

いまいち追いきれない……
一部にdumpStack入れたものをcommitしたので，
NPEが出たらその手前にあるであろうdumpStackの結果を
貼り付けてもらえまつか．

いや、それだと試したけどdumpStackでない。
さらに試しに
Thread.dumpStack();
System.err.println("thread.logFolder : " +
thread.logFolder.getFullPath());
System.err.println("logFolder: " + logFolder.getFullPath());
System.err.println("thread.id : " + thread.id);
System.err.println("id : " + id);
return thread.logFolder.equals
(logFolder) && thread.id.equals(id);
ってやって最後の一行にブレークポイントあてて実行すると、
java.lang.Exception: Stack trace

...(中略)...
thread.logFolder : /2ch.net/log716
logFolder: /2ch.net/log716
thread.id : 1031235104.dat
id : 1031235104.dat
まで出てブレークポイントで止まる。で、ステップインを一度
行うとそこで、NPE.
ところで明日から一週間出張で不在なのでこれ以上おえません。

激しく不思議な挙動やね……
logFolderのequalsの中で飛んでるならわかるが．
大体こういう意味不明な場合は
typoで間違ったフィールド参照してたり
するもんだけど，そうでもないみたいだしw

return thread.logFolder.equals(logFolder) && thread.id.equals(id);
を
boolean logEq = thread.logFolder.equals(logFolder);
boolean idEq = thread.id.equals(id);
return logEq && idEq;
とかにして，どっちで飛んでるのか見てみてほしい．

あと，jreとeclipseとWindowsのバージョンも教えてくだちい．
