I also noticed some exceptions on running (but only visible in log) ->

is it something I have to worry about?
If it's only visible at DEBUG-level it probably is not harmful that
much. I only wonder if class not found exceptions would not become a
performance bottleneck but I'm not really sure. If someone is going to
investigate a performance problems it is a thing to look at.
Spring comes with a spring.handlers file in spring-beans.jar/META-INF
which holds the references to those files mentioned above. If other
module jars like ejb and tx are not included the exception is thrown.
That issue is only fixed on 2.1 branch of Spring:
