After updating our Vibe server to 4HP2, every try to connect fails with the browser message

HTTP Status 500 - Error creating bean with name 'sPropsUtil' defined in ServletContext resource [/WEB-INF/context/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationExcepti on: Could not instantiate bean class [org.kablink.teaming.util.SPropsUtil]: Constructor threw exception; nested exception is java.lang.IllegalStateException: PropsUtil is a singleton class
The log path /opt/novell/teaming/apache-tomcat/webapps/ssf/WEB-INF/logs does not exist and the tomcat log gives the same message, bean can not be created.

I tried the things I found round the forums about the and the kablink.encryption.key but the key is the same in the old and the new version so it seems to be something else. If anyone has a good idea or a hint how to get rid of this problem it would be great.

SR has also been made.
