log4j 構成ファイルとコードがここにありません。

しかし、最初の推測は、

1) LoggingOutputStreamはコードのどこかで使用され、System.err次のように置き換えられます。

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

2) log4j が適切に構成されておらず、内部エラーを LogLog に出力しようとしてSystem.errいます。

これにより、循環ロギング呼び出しが作成され、スタック オーバーフローが発生します。

System.err1) からインターセプターを削除してみてください)。これにより、2) の内部エラーが表面化する可能性があります。
