For me, the exception keeps reappearing even after restart, when projects are reloaded. Completing the update of the J2EE modules to 8.0.1 resolves the problem.
Not sure if other reports come from the same scenario.

caused by version clash between maven and maven.j2ee
upgrading J2EE modules should fix the problem.
