Fixes potential NPE while reading annotations

[gastaldi]

An NPE may happen in methods returning an exception without the @TransformException annotation

Actually this happens because the jboss-logging-annotations from the parent POM is 2.2.1.Final, explicitly declaring to use 3.0.0.Final makes the error go away.

I'll let you decide if this PR is worth including in the next release ;)
