> In Zookeeper 3.3.x you use log4j for logging, and the maven dep is
> eg from 3.3.4
> {code}
>     <dependency>
>       <groupId>log4j</groupId>
>       <artifactId>log4j</artifactId>
>       <version>1.2.15</version>
>       <scope>compile</scope>
>     </dependency>
> {code}
> Now in 3.4.0 or better you changed to use slf4j also/instead. The maven pom.xml now includes:
> {code}
>   <dependency>
>       <groupId>org.slf4j</groupId>
>       <artifactId>slf4j-api</artifactId>
>       <version>1.6.1</version>
>       <scope>compile</scope>
>     </dependency>
>     <dependency>
>       <groupId>org.slf4j</groupId>
>       <artifactId>slf4j-log4j12</artifactId>
>       <version>1.6.1</version>
>       <scope>compile</scope>
>     </dependency>
>     <dependency>
>       <groupId>log4j</groupId>
>       <artifactId>log4j</artifactId>
>       <version>1.2.15</version>
>       <scope>compile</scope>
>     </dependency>
> {code}
> But the META-INF/MANIFEST.MF file in the distribution did not change to reflect this.
> The 3.3.4 MANIFEST.MF, import packages
> {code}
> Import-Package: javax.management,org.apache.log4j,org.osgi.framework;v
>  ersion="[1.4,2.0)",org.osgi.util.tracker;version="[1.1,2.0)"
> {code}
> And the 3.4.1 MANIFEST.MF, import packages:
> {code}
> Import-Package: javax.management,org.apache.log4j,org.osgi.framework;v
>  ersion="[1.4,2.0)",org.osgi.util.tracker;version="[1.1,2.0)"
> {code}
> This makes using zookeeper 3.4.x in OSGi environments not possible, as we get NoClassDefFoundException
for slf4j classes.
