Jonathan Halliday commented on JBTM-328:
----------------------------------------
Both threads can get null, but only one will create the mapping. The other will be blocked
on the synchronized createMappings method. When it gets the lock and goes into the create
method if will first try (and succeed) with another get attempt and create a new entry
only if it's still getting null.
