How do I stop stacktraces truncating in logs

Question

Lots of times in Java logs I\'ll get something like:

Caused by: java.sql.BatchUpdateException: failed batch
    at org.hsqldb.jdbc.jdbcStatement.executeBatch         


        

Answer 1

Apache's Commons Lang provides a nice util method ExceptionUtils.printRootCauseStackTrace() which prints a nested stacktrace 'upside down'. The result is much more intuitive.

If you see the result next to the original out of the printStackTrace() method, it will be clear where the '113 more' lines went.
