    Description

      When processing environment variables for a container context the code assumes that the value should be appended to any pre-existing value in the environment. This may be desired behavior for handling path-like environment variables such as PATH, LD_LIBRARY_PATH, CLASSPATH, etc. but it is a non-intuitive and harmful way to handle any variable that does not have path-like semantics.
