in case hostAddresses was null, the isEmpty() check before the log()
invocation would throw an NPE. Thanks to Ingo Bauersachs for reporting
this.
Fixes SMACK-788.

SMACK-343
In dd84d53bbc the usage of dynamic

them, i.e. the '1.2.+' notation, on release artifacts. But they allow
the mathematical range notation '(1.2,1.3]', therefore we use this now.
