The MANIFEST currently imports org.slf4j with minimum version 1.7.7. Please consider to change that to minimum version 1.7.
Background: We use Mina in the Apache Directory LDAP API, which is used in Apache Directory Studio. Studio is based on Eclipse which already contains an slf4j-api bundle (org.slf4j.api_1.7.2.v20121108-1250.jar). We additionally added slf4j-api 1.7.10, however that causes issues, see
DIRSTUDIO-1068 for details.
I'll attach a patch, with that change it is possible to reuse the existing slf4j-api 1.7.2 provided by Eclipse.
