WARNING: Multiple extension implementations found

mwtemple Apr 6, 2011 11:27 PM

Is this something to be concerned about?

JUnit Console:

Apr 6, 2011 9:17:05 PM org.jboss.shrinkwrap.impl.base.ServiceExtensionLoader findExtensionImpl

WARNING: Multiple extension implementations found for org.jboss.shrinkwrap.api.spec.JavaArchive, please verify classpath or add a extensionOverride

I then see some ugly stuff in the JBoss Console:
