Rewritten @Cleanup's new null analysis prevention to not use

Lombok.preventNullAnalysis but go with Collections.singletonList(expr).get(0)
instead; while this does create a pointless object, it doesn't cause a clash
when eclipse has lombok 0.10 installed but the project uses 0.9, which doesn't
have preventNullAnalysis. Eventually, once 0.9 is long forgotten, this can be reverted.
