Description

When used in a Tomcat servelet LoggerBridge has a different class loader to JDKLoggerBridge  so when it dose if (service.isAssignableFrom(clazz)) { in java.util.ServiceLoader it fails.

took the source to 3.0.3 and replaced all.

private static final Logger log

with

private final Logger log

and also added , Thread.currentThread().getContextClassLoader() as a parameter to LoggerFactory.getLogger .

 

This fixed the problem for me, not too sure if Thread.currentThread().getContextClassLoader() is over kill as I think it is the static that is causing the problem.
