Indeed. Logback assumes that the stack trace element occurring just after logback's external boundary is that of the caller. Here is the relevant stack trace as seen by logback when invoked by groovy.

note: c.q.l.c stands for ch.qos.logback.classic

<br/>
c.q.l.c.Logger.appendLoopOnAppenders(Logger.java:280) <- within logback
<br/>
c.q.l.c.Logger.callAppenders(Logger.java:267) <- within logback
<br/>
c.q.l.c.Logger.buildLoggingEventAndAppend(Logger.java:449) <- within logback
<br/>
c.q.l.c.Logger.filterAndLog_0_Or3Plus(Logger.java:403) <- within logback
<br/>
c.q.l.c.Logger.debug(Logger.java:510) <- within logback (external boundary)
<br/>
org.slf4j.Logger$debug.call(Unknown Source) <- caller according to logback
<br/>
org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:45)
<br/>
<br/>
org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:108)
<br/>
org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:116)
<br/>
com.foo.LineNumTest.foo(LineNumTest.groovy:13) <- actual caller

Logback needs to adjust it's algorithm so that the caller is assumed to be following "org.codehaus.groovy.runtime.callsite". Presumably, the fully defined class name of the caller depends on the version of grovvy, i.e it may not always be "org.codehaus.groovy.runtime.callsite". To accommodate that
<br/>
possibility, logback can check for the more generic "org.codehaus.groovy".
