Eccezione profondità nel log4j

Question

Im ottenendo un'eccezione di istanza nell'applicazione Myfaces 2. Ma la stampa dell'eccezione tramite log4j sta tagliando il resto dello stacktrace. Ecco quello che sto vedendo:

non riesco a trovare dove cambiare la configurazione così posso vedere il "... 48 altro". Qualche idea?

Answer 1

Non è possibile. Il troncamento della traccia dello stack è una funzione di JVM, non di log4j.

In realtà è solo scartando le informazioni che già ti ha presentato. ... 48 more è una stenografia per the 48 frames that preceded the "Caused by" message. Quindi, nel tuo caso, i 48 frame elided sono:
