I have 2 servers running PDI CE. The older one runs the 5.4.0.0-128 and all run smoothly, the newer one runs the last version 6.1.0.1-196.
The 2 servers run the same jobs (I'm migrating from the older server to the newer one) that are saved in a file system repository.
I'm experiencing some errors running jobs on the new server.
2 of these errors are about Karaf and 1 is about SLF4J.

This is the first one that seems to come out sometimes if I run my jobs while spoon is open.
