In my case it was a version conflict caused by activemq-all. That dependency (5.12.2 in my case) includes an incompatible version of spring (I just upgraded to spring 4.3.4). So, save yourself a few hours of debugging and check not only the Dependency Hierarchy in your favorite IDE, but also look inside those jar files to see if any are embedding org.springframework packages.

Answer 3

It is probably a version conflict since you are using a old version of base spring (2.5.6) with very new one (4.1.4.RELEASE) for your test en context includes
