Changes to the factories are visible after the method ends, all
iterators (availableCharFilters()
,...) stay consistent.
NOTE: Only new factories are added, existing ones are never removed or replaced.
This method is expensive and should only be called for discovery of new factories on the given classpath/classloader!
