Description Jonathan Camilleri CLA 2011-04-24 08:59:58 EDT
Build Identifier: Build id: M20110210-1200

It seems that including a logger object, results in multiple lines (in my case 6 lines) being returned, for example:

...
_log.debug("Cards held by dealer:");
...

results in
0 [main] DEBUG poker.Poker  - Cards held by dealer:
0 [main] DEBUG poker.Poker  - Cards held by dealer:
0 [main] DEBUG poker.Poker  - Cards held by dealer:
0 [main] DEBUG poker.Poker  - Cards held by dealer:
0 [main] DEBUG poker.Poker  - Cards held by dealer:
0 [main] DEBUG poker.Poker  - Cards held by dealer:

being displayed within the Console window.

whilst coding 'System.out.println("Cards held by dealer:");', results in:

'Cards held by dealer:' being displayed within the console window.



Reproducible: Always

It seems that bug #331160 reported a similar issue, however it is assigned to a dummy inbox.

Does the multiple logging also occur when you launch the example on the command line?

Well, somehow I'm getting a bunch of compilation errors when trying to compile through the command line, so it appears I have some debugging to do, however, I can't really understand why it seemed to be working within eclipse on 24.04.2011, and, I haven't changed much about Eclipse, although the source code has changed in the meantime.

However I tried running the command line on the source code originally attached.

@echo off
set CLASSPATH=.
javac *.java
java -Dlog4j.debug=true Poker
pause

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
