hi,
I get a "java.lang.ClassCircularityError: java/util/logging/LogRecord"
error when I try to start my web-app in tomcat 7.
first I call:
SLF4JBridgeHandler.install();
and then wehn I try to log to a java.util.Logger, I get the exception
(stack trace below)
this happens only when I use the LevelChangePropagator (in my logback.xml file)
<contextListener
class="ch.qos.logback.classic.jul.LevelChangePropagator">
</contextListener>
If I son't install the LevelChangePropagator I get no exception and
the JUL logging is routet to the slf4j logging.
I am using Tomcat 7.
does anyone have an idea, what the problem could be?
I didn't find much usefull info about the java.lang.ClassCircularityError.
cheers, Martin
