When performing a m2release it performs everything correctly, and then the artifactory plugin tries to deploy the next snapshot artifacts, and I get the stack trace that follows. As you can see the m2release completes successful. It correctly deploys the next snapshots jar, and fails on the pom. I traced it to the ArtifactDeployer and ensured that the source pom file exists on the hudson server running the release. The wording of the IO error is a little odd. Makes me think that the IO error is wrapped. I verified this by breaking on IOExceptions and it threw quite a few. That is when I gave up and decided to file a ticket.
