Steve Cohen commented on LBCLASSIC-305:
---------------------------------------
After stepping through code it seems that the problem is that when filtered
through LocationAwareLogger.log(), the new Throwable() call does not fill in a
correct stack trace, but when going through a method such as Logger.debug(),
the call to new Throwable() DOES produce a correct stack trace (albeit
non-location-aware). This is why my original bandaid in see
http://jira.qos.ch/browse/LBCORE-233) works, but this does not.
Hard to tell what's going on here because Throwable.fillInStackTrace() is
native code. However, I don't suspect platform implementation because this
issue was originally noticed (see http://jira.qos.ch/browse/LBCORE-233) on a
Windows XP platform using Sun Java 1.6, whereas this test was on Ubuntu Linux
using Sun Java 1.6.

> Key: LBCLASSIC-305
> URL: http://jira.qos.ch/browse/LBCLASSIC-305
> Project: logback-classic
> Issue Type: Bug
> Affects Versions: 1.0.0
> Reporter: Steve Cohen
> Assignee: Logback dev list
> Attachments: logback-bug.zip

>
> 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
