Description

Several framework and extension components have direct dependencies on various versions of Google Guava.  Older versions of Google Guava have multiple vulnerabilities, and the library itself is almost 3 MB.  For components that have minimal usage of Guava, implementations should be refactored to use available JDK utilities or alternative caching libraries that have a smaller footprint.
