There is an exception that appears when the Switchyard Library Integration Test is executed:

<system-err>org.osgi.framework.BundleException: Uses constraint violation. Unable to resolve bundle revision org.jboss.weld.osgi-bundle [110.0] because it is exposed to package 'javax.el' from bundle revisions org.ops4j.pax.web.pax-web-jsp [173.0] and javax.el-api [99.0] via two dependency chains.

Chain 1:

import: (&(osgi.wiring.package=javax.el)(version>=1.0.0))

export: osgi.wiring.package=javax.el

Chain 2:
org.jboss.weld.osgi-bundle [110.0]
