BeanInfo#collectParameterAnnotations using a great deal of CPU time
I'm relatively new to Camel, but we've been using it for quite some time on
my project. Today, I noticed that even when our system is relatively
lightly loaded, the BeanInfo#collectParameterAnnotations() method is listed
in JVisualVM CPU sampling as using 26% of our total CPU time. This seems
extremely high to me, and I was wondering if this might be an indicator that
we are misusing Camel?
We're using Java 7 under Tomcat 7.0.56, and an older version of Camel
(2.10.4).
Thanks in advance!

Thanks. I'll give that a try as soon as we get time to do the upgrade.

That is a an old version of Camel. The bean introspection has a local
cache so the introspection cost is only once. As you use such an old
version I am not sure it includes that cache and other improvements we
have done since.
You can try upgrade and see what yourkit says in a never version.
