Hendrik Schöneberg commented on CAMEL-5457:
-------------------------------------------
Hey,
I created a small project and am able to reproduce the NPE in about 30% of all
startups. See attached NPETest.zip for the project's setup. The snippet tries
to load a beans.xml from the classpath (ie, from within lib/resources.jar) and
instantiates a simple bean. I also included a build.gradle from which you can
derive the dependencies and their respective versions.
I will test the snippet with Spring 3.0.7 and 3.1.1 as you suggested.
Kind regards!
