Adding picketlink to my pom.xml creates issues - jboss

Question

I have being dealing with this issue since yesterday and I have being able to fix it.
I added this
<dependency>
<groupId>org.picketlink</groupId>
<artifactId>picketlink-api</artifactId>
<scope>compile</scope>
<version>${picketlink.version}</version>
</dependency>
<dependency>
<groupId>org.picketlink</groupId>
<artifactId>picketlink-impl</artifactId>
<scope>runtime</scope>
<version>${picketlink.version}</version>
</dependency>
to my pom.xml and at first i didnt now what was the problem, because sometimes in worked some times it didnt.
So if I add picketlink to my pom.xml (I tried many options from the picktlink quickstarts, and versions), and it runs the first time, but if I recompile it again and try to replace my .war file I get and error and I have to delete the data/* tmp/* folders and restart my jboss.
This is the error
