patch applied with open OSGi version range 3.7.0

Please, how can I get list of plugins which has to have updated MANIFEST.MF

They are the same plugins that has dependency to org.jboss.tools.usage.
Something like command below should do the trick

find jbosstools-src/jmx -name *.MF -exec grep -l 'usage' {} \;

These plugins have dependency on org.jboss.tools.usage plugin and doesn't have version restriction for org.eclipse.core.runtime plugin:

org.jboss.tools.modeshape.rest_1.1.0.v20111022-0835-H25-M4
org.jboss.ide.eclipse.freemarker_1.2.0.v20111022-0834-H30-M4

org.mozilla.xpcom_1.9.2.16 - is dependent on 'usage' plugin but is not dependent on 'runtime' plugin so probably manifest file is correct?

org.mozilla.xpcom is fine without this dependency, because it just pure java libraries for JavaXPCOM bridge.
I've fixed fremarker in trunk.

modeshape shouldn't have one because this fix is for JBoss Tools Indigo installation from Eclipse Marketplace where modeshape is not present.

Missing version range in freemarker is not a blocker for M4.
Resolving.

I've added open version range (3.7.0) or org.eclipse.core.runtime in modeshape plugin as well to make it work the same way for normal installation from update site.

Fix for freemarker plugin is not reason to respin 3.3.0.M4. Verified that fix is commited in trunk so it will be fixed in next version.
