Alexey Kazakov commented on JBDS-4136:
--------------------------------------
Yes, this is the plan to use m2e 1.7.1 it in devstudio when the 1.7.1 release is available. When it's done then it's not critical to fix slf4j in rh-java-commons (we need to test it though) but IMO renaming the slf4j bundle name in rh-java-commons should be considered anyway. It can affect other Eclipse plugins which may use Require-Bundle instead of Import-Package.

> I suppose the best case would be for the m2e and w2e-wtp bundles to depend on the slf4j.api PACKAGES instead of BUNDLES, so that they can run on the fedora/rhel versions instead of those from the devstudio update site / target platform.
