Dag H. Wanvik commented on DERBY-5567:
--------------------------------------
For the record, the reason the dependencies are sometimes accessed in a
different order is the fact they are held in a hash table keyed by their UUID,
cf.
ProviderList.addProvider. Although the dependencies are always added in the
same order in the bind phase, when they are retrieved, they may come back in a
different order, cf BasicDependencyManager.getÅersistentProvideInfos which
retrieves an Enumeration from the hash table.
