Question

これは、stackoverflowサイト上の実際のstackoverflow例外です！私はちょうど誰かが以前にそれを見ていたかどうか、そして彼らがそれに対処するために使用したものを疑問に思った

java.lang.StackOverflowErrorを

Answer 1

ここにあなたのlog4j設定ファイルとコードがありません。このようSystem.errを交換

しかし

1）LoggingOutputStreamコードのどこかで使用されていること初期推定は、：

System.setErr(new PrintStream(new LoggingOutputStream(Category.getRoot(), Priority.WARN), true)); 

2）log4jは適切に設定され、System.errに内部エラーを印刷しようとしていませんLogLogにあります。

これは、スタックオーバーフローを引き起こす循環ログ呼び出しを作成します。

1）からSystem.errインターセプターを削除してみます。これにより、2）の内部エラーが発生する可能性があります。
