Hmmm, these looks like a problem in Hibernate Search since they're the ones using slf4j.

I don't see why Infinispan Query should explicitly declare a dependency on slf4j.

Emmanuel, wdyt?

http://anonsvn.jboss.org/repos/hibernate/search/tags/v3_2_0_Final/hibernate-search/src/main/java/org/hibernate/search/util/LoggerFactory.java needs slf4j, so it would appear to me that Hibernate Search should define dependencies on slf4j and not query module.

I see https://repository.jboss.org/nexus/content/groups/developer/org/hibernate/hibernate-search-parent/3.2.0.Final/hibernate-search-parent-3.2.0.Final.pom having the same stuff query has, a dependency on slf4j-log4j with test scope.
