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 ssf-ext.properties 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.
