code:
with apache-jena-libs in pom
Finding only one init is a symptom repacked jars that have not the right
ServiceLoader files.
It looks like classpath has a repacked set of jena jars on it or a jar
with jena inside it, as well as those from apache-jena-libs. The
repacking did not merge the ServiceLoader files.
If it not a case of unjar, copy into one place and rejar.
http://jena.apache.org/documentation/notes/jena-repack.html
What to look for:
in any jars
META-INF/services/org.apache.jena.sys.JenaSubsystemLifecycle
it should have multiple lines in it if it has multiple Jena jars
combined in it (example from the Fuseki server jar):
org.apache.jena.tdb.sys.InitTDB
org.apache.jena.riot.system.InitRIOT
org.apache.jena.sparql.system.InitARQ
org.apache.jena.sys.InitJenaCore
org.apache.jena.tdb2.sys.InitTDB2
org.apache.jena.query.text.InitJenaText
org.apache.jena.query.spatial.InitJenaSpatial

And no output? DEBUG_INIT causes init() to print all details of startup.
The first thing the code does is print "JenaSystem.init - start" even
before it's got to looking for components to initialize.
See my other code experiment which is Jena-only code - no 3rd party code.
Can you share the POM?
