I think we could update the low-risk dependencies (test-time, log4j, &c), while avoiding those we know will be trouble (jetty). This may seem minor but it does make a big diff to the downstream projects. -- CONFIDENTIALITY NOTICE NOTICE: This message is intended for the use of the individual or entity to which it is addressed and may contain information that is confidential, privileged and exempt from disclosure under applicable law.
