The integration test logs are weird because of running Jetty in a
separate process. I usually run the IdP by hand :

cd java-idp-integration tests
mvn clean package -DskipTests
cd test-distributions/idp-distribution-3.0-SNAPSHOT/jetty-base/
java -Dlogback.configurationFile=../conf/logback.xml -jar
../../jetty-distribution-9.2.3.v20140905/start.jar | tee OUT

Here's the exception I was seeing :

Caused by: java.lang.IllegalStateException: No
