-------------------------------------

> In my case I'm only deploying jackrabbit-jcr2dav and jackrabbit-spi2dav - no 
> wars, nothing extra yet, and none of this works out the box. I want to fix

The right fix is to identify the problem and fix it. It's supposed to work. Of 
cource you *could* fork Jackrabbit and ove to a different logging API, but of 
course forking comes with disadvantages.

>Moving on to the test suite, when the jackrabbit test suite is run from within 
>Eclipse, we get this logged complaining about multiple slf4j bindings, and 
>nothing logged from the test itself:

Which subproject? And is this reproducable directly from Maven?




> Remove slf4j from Jackrabbit libraries

> Life is too short to deal with exceptions like this one:
> java.lang.LinkageError: loader constraint violation: when resolving method

> org.slf4j.impl.StaticLoggerBinder.getLoggerFactory()' the class loader 
> org.apache.catalina.loader.ParallelWebappClassLoader @4bd217c of the current 
> class, org/slf4j/LoggerFactory, and the class loader java.net.URLClassLoader 
> @7907ec20 for the method's defining class, org/slf4j/impl/StaticLoggerBinder, 
> have different Class objects for the type org/slf4j/ILoggerFactory used in 
> the signature (org.slf4j.LoggerFactory is in unnamed module of loader 
> org.apache.catalina.loader.ParallelWebappClassLoader @4bd217c, parent loader 
> java.net.URLClassLoader @7907ec20; org.slf4j.impl.StaticLoggerBinder is in 
> unnamed module of loader java.net.URLClassLoader @7907ec20, parent loader 
> 'app')
> Remove slf4j and replace with the java default behaviour.
