Following the instructions in quickstarts/switchyard/demos/policy-security-wss-signencrypt/Readme.md the test cannot pass.

While running the last command that should successfully pass (mvn exec:java -Dexec.args="confidentiality signencrypt" -Djavax.net.ssl.trustStore=connector.jks), it fails and an exception is thrown. Especially "Unable to load class" and "Class cast exception" look suspicious.
