Description
When running several WAR files under one appserver, and both WAR files create one or several MongoClient instances, with 2.12.0-rc0 we start seeing

This happens for the second WAR file starting (first one works fine, even though it started several instances of MongoClient). If we load only one of the WAR files (no matter which) this does not happen.
This is working fine if using 2.11.4 (and a few earlier versions, for sure) of the driver but broke in 2.12.0-rc0
