IllegalTransactionStateException when running in Jetty - spring

Question

I have a WAR application as follows:
JPA/Hibernate 4.1.9.Final
Hibernate Envers 4.1.9.Final
Spring 3.1.3.RELEASE
Spring MVC with JSON/REST
My frontend (web page) makes a request, this leads to a new entity to be saved (this seems to succeed in any case) and then Envers will save corresponding revision info.
Typical deployment is in Tomcat 7, where this works just fine.
For unit testing I spin up a Jetty (8.1.9.v20130131) programmatically, which fails. It baffles me why this behavior is different. I can only imagine that Jetty has a different (lesser standard, perhaps) transaction management on board than Tomcat, but I've failed to pin it down or otherwise work around this.
Below is how I create the web application programmatically:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration({"classpath:applicationContext.xml" })
public class AddCustomerTest {
And:
server = new Server(serverPort);
WebAppContext webAppContext = new WebAppContext();
webAppContext.setContextPath("/webapp");
webAppContext.setWar("src/main/webapp");
webAppContext.setServer(server);
server.setHandler(webAppContext);
Below is the essential exception that I'm getting:

My RevisionEntityListener looks up some user data (from the database, using Hibernate of course). Clearly there's no transaction available, but only when running in Jetty. I've tried marking the RevisionEntityListener transactional in various ways, to no avail.
Let me know if you need any other info. Your help much appreciated!

Stupid me...
The following two lines were copied over from some other test class:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration({"classpath:applicationContext.xml" })
These two lines served no purpose since the entire application was loaded through the instantiation and configuration of Jetty. But somehow the above clashed with the application in the Jetty server, probably due to being in the same JVM. Removing the above two lines from the test class fixed it!
