[SOLVED] Is xws-security incompatible with Java 8?

I implemented a SOAP web service server and client (based on http://spring.io/guides/gs/producing-web-service/). The communication is encrypted with a symmetric 24-bit DESede key.

When the client is compiled with JAVA target runtime 1.7 it can successfully exchange messages with the server. However after changing the runtime to 1.8 the following exception is thrown:

The XMLCipher class is loaded from:

Is this a bug in Java 8 or do I have to update the dependencies?
