question: public void printStackTrace ( java . io . PrintStream s ) { if ( s == null ) s = System . err ; try { super . printStackTrace ( s ) ; } catch ( Exception e ) { } Throwable exception = m_exception ; for ( int i = 0 ; ( i < 10 ) && ( null != exception ) ; i ++ ) { s . println ( "---------" ) ; exception . printStackTrace ( s ) ; if ( exception instanceof TransformerException ) { TransformerException se = ( TransformerException ) exception ; Throwable prev = exception ; exception = se . getException ( ) ; if ( prev == exception ) break ; } else { exception = null ; } } }
target:  Print the the trace of methods from where the error originated.  This will trace all nested exception objects, as well as this object.
