[logback-dev] [JIRA] Updated: (LBCLASSIC-305) Logger does not implement LocationAwareLogger correctly with Wrapper class

[Steve Cohen (JIRA)]

Steve Cohen updated LBCLASSIC-305:
----------------------------------

    Attachment: logback-bug-2.zip

In this version of the project (logback-bug-2.zip) it's a bit easier to see what's going on.  This version rewrites LogHelper so that trace(...) delegates to Logger.trace() whereas all the other levels delegate, as before, to LocationAwareLogger.log().  It shows that the former does find correct (but, of course, non-location-aware) stack traces to work with but the latter does not find correct stack traces.

Output:

2011-11-07 08:28:23,230 DEBUG [main] ?#?:?
 - Constructor of A
2011-11-07 08:29:30,554 TRACE [main] Caller+0	 at org.javactivity.LogHelper.trace(LogHelper.java:51)
 - A()
2011-11-07 08:34:42,981 DEBUG [main] Caller+0	 at org.javactivity.A.<init>(A.java:10)
 - Constructor of B
2011-11-07 08:35:16,844 TRACE [main] Caller+0	 at org.javactivity.LogHelper.trace(LogHelper.java:51)
 - B()

> As shown in the attached project, we are logging using Logback classic through a wrapper class (LogHelper), with formatting specified by the %caller format specifier.  Instead of showing the desired actual caller of the LogHelper.debug() method, the output shows as the caller, the caller of the caller of the logHelper.
> I'm expecting: 
> 2011-11-06 18:49:59,650 DEBUG [main] Caller+0	 at org.javactivity.A.<init>(A.java:8)
>  - Constructor of A
> 2011-11-06 18:49:59,654 DEBUG [main] Caller+0	 at org.javactivity.B.<init>(B.java:7)
>  - Constructor of B
> Instead I get:
> 2011-11-06 18:49:59,650 DEBUG [main] ?#?:?
>  - Constructor of A
> 2011-11-06 18:49:59,654 DEBUG [main] Caller+0	 at org.javactivity.A.<init>(A.java:9)
>  - Constructor of B
