[infinispan-dev] Issue posted for JBoss Logging and slf4j

[David M. Lloyd]

Due to the lack of a logging backend JAR, I am assuming that you are 
using java.util.logging for your logging backend.  There is nothing in 
JBoss Logging which handles appenders or handlers or logs messages in a 
loop of any kind; thus I think the most likely situation is that there 
are multiple log backends being configured at a JUL level.  Apart from 
the obvious "check the logging config file" [1] [2], it's quite possible 
that one or more JARs on the classpath are "helping" you by configuring 
additional log handlers on JUL's root logger programmatically.  I can 
tell you that neither JBoss Logging nor JBoss Marshalling does this, but 
beyond that I cannot say.
