I think it means that commons-logging jar is not compatible with slf4j jar.
Can you search and make sure there is only one of each of those jars in all
the lib dirs?

Sorry, the memory difference between the two machines is a red

I swapped the set of ldappc-ng jars (both built with maven
from source) and the behavior swapped.

The two OS installations are the same.

The only difference is that one set of jars was built last
week and one set was built today.

Since maven is being used to build from source, is it possible
that today's build process downloaded some broken code that
was not downloaded last week?
