The 1.0-alpha-2 version is still used by camel-jms and camel-sjms2 components as JMS 2.0 API dependency.
The javax.jms/javax.jms-api/2.0.1 is already available in Maven centre (provided by Oracle).
There are options, 1) using this javax.jms/javax.jms-api/2.0.1 directly, as it's already OSGi friendly. 2) wrap a servicemix one for it.
Is License a problem? I see the javax.jms/javax.jms-api/2.0.1 is CDDL.
