The same NPE I get with old build 1.1.0-SNAPSHOT-20150129-1515 while the much more older Version 1.1.0-rc5 ist working fine

Can you give some more information about the environment you are running the app in.
Did you use the bundled-jar-cifs build profile? Because otherwise the config files and the cifs you get the NPE for are missing.

I downloaded the single JAR file (richclient-1.1.1-20150724-0916.jar) only, mentioned in JNPL file: http://jnlp.openecard.org/openecard.jnlp because this was working in past and I'm doing my tests in some restricted environment and I'm using the Client as offline stand alone version.
<!-- <jar href="OpeneCardApp.jar" version="1.1.1-20150724-0916" main="true" />--> ---> this line is commented out
<jar href="richclient-1.1.1-20150724-0916.jar" main="true" />
<jar href="cifs-1.1.1-20150724-0916.jar" download="lazy" />

Edit:
If I need both JAR files richclient & cifs during runtime now, I understand the problem, but need a stand alone version, as any (CIFS) access to outside is blocked.

Nevertheless the NPE should be catched and a proper error message should be displayed (e.g. "missing resources, wrong client code started, ...."). Sometime that indicates, that the downloaded client can not run and another package is required.

The OpeneCardApp.jar is a comment in the jnlp file.

The required jar files are the richclient-1.1.1-20150724-0916.jar and the cifs-1.1.1-20150724-0916.jar. Both are needed to start the Open eCard App so it is necessary to have both files. Prior versions did not have the cifs[...].jar because the included files were part of the richclient jar.

Your downloaded source is from a link in an jnlp file. An jnlp file is normally used with java webstart which doesn't seem to be appropriate for your setup.

So there are two options i think.

1. Try to copy the cifs jar into the class path (not tested)

or

2. Build a bundled version which contains all required files.
Basic instructions for the required system setup and how to get the code are provided in the wiki https://dev.openecard.org/projects/open-ecard/wiki/Getting_Started

If you have the code you just have to do an 

mvn clean install

After the build the richclient jar is available in clients/richclient/target and there the file with the name richclient-{version}-bundle-cifs.jar

A small correction from my side.
In order to build a bundled version the profile I mentioned earlier must be added manually. 

mvn -P bundled-jar-cifs clean install

In order to run the JNLP jars the following line works for me.

java -cp cifs-1.1.1-20150724-0916.jar:richclient-1.1.1-20150724-0916.jar org.openecard.richclient.RichClient

When trying to run as a combination of $-cp$ and $-jar$ the $-cp$ seems to be ignored.

By the way, we stopped providing the bundled version as we want everybody to receive upgrades which is the case with JNLP. It should also work offline. If not we should take care of that issue again. However this still needs a connection in the first place to download the jars. For the future I think your best bet is to use a build you did by yourself.

To build my own bundle is no option, for some reason, but your hint about the start with combined classpath works fine

  java -cp cifs-1.1.1-20150724-0916.jar;richclient-1.1.1-20150724-0916.jar org.openecard.richclient.RichClient

This starts the richclient without an exception. :-)

But as an improvement I still suggest to catch the NPE to show a proper error message.
