java.lang.StackOverflowError

Answer 1

buradan log4j yapılandırma dosyaları ve kod eksik. Böyle System.err değiştirilmesi

Ama

1) LoggingOutputStream kodunda bir yerde kullanıldığını ilk tahminim olduğunu:

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

2) log4j düzgün yapılandırılmış ve System.err iç hatayı yazdırmaya çalışır değildir LogLog.

Bu, yığın taşmasına neden olan dairesel günlük aramaları oluşturur.

1) 'den gelen System.err durdurucuyu kaldırmayı deneyin. Bu, 2) 'deki dahili hatanın yüzeye çıkmasına izin verir.
