[WFLY-1242] use JBossLogPrintWriter to output log information to jboss logging

https://issues.jboss.org/browse/WFLY-1242
JBossLogPrintWriter is like "adapter" pattern, it will intercept all print and output to jbosslogging. Since we need a 'PrintWriter' to construct JBossLogPrintWriter, we just use 'system.out'. But it isn't work here.
