Stefan Seelmann commented on DIRSTUDIO-1068:
--------------------------------------------

Wow, thanks you very much for the detailed diagnostics and description of the 
problem.

The slf4j-api 1.7.10 bundle is the original one, downloaded from maven central. 
this contains the Import-Package statement. We should consider to exclude it 
and use the org.slf4j.api_1.7.2.v20121108-1250.jar which seems to be modified 
bacause it lacks the Import-Package statement. Still the 
org.slf4j.LoggerFactory class imports {{org.slf4j.impl.StaticLoggerBinder}}...

To test the changes checkout the Studio sources. Please see the developer guide 
https://directory.apache.org/studio/developers-guide.html and the readme 
https://github.com/apache/directory-studio. The main pom.xml already contains 
the new LDAP API 1.0.0-M31 dependency.
