<p style='margin-top:0;margin-bottom:10px;'>This issue reports on a regression introduced in 1.1.*. In 1.0.13 the following test program:</p>
<p style='margin-top:0;margin-bottom:10px;'> import org.slf4j.Logger;<br/>
import org.slf4j.LoggerFactory;</p>
<p style='margin-top:0;margin-bottom:10px;'> public class Test<br/>
{<br/>
private static final Logger LOGGER = LoggerFactory.getLogger(Test.class);</p>
<p style='margin-top:0;margin-bottom:10px;'> public static void main(String[] args)<br/>
{<br/>
LOGGER.warn("foo {} {}", "bla", new Exception("bar"));<br/>
}<br/>
}</p>
<p style='margin-top:0;margin-bottom:10px;'>logs </p>
<p style='margin-top:0;margin-bottom:10px;'> 11:45:29.278 <span class="error">[main]</span> WARN Test - foo bla java.lang.Exception: bar</p>
<p style='margin-top:0;margin-bottom:10px;'>In 1.1.1 the same program logs:</p>
<p style='margin-top:0;margin-bottom:10px;'> 11:46:03.664 <span class="error">[main]</span> WARN Test - foo bla {}<br/>
java.lang.Exception: bar<br/>
at Test.main(Test.java:14) <span class="error">[tmp/:na]</span></p>
<p style='margin-top:0;margin-bottom:10px;'>Thus in 1.1.1 logback unconditionally removes the exception from the argument array and logs the stack trace despite there being a placeholder for it in the pattern.</p>
<p style='margin-top:0;margin-bottom:10px;'>Since SLF4J has a special method for the case of logging an exception (Logger#warn(String,Throwable)), I would expect the the behavior observed with 1.0.* to be the correct one.</p>
