Apache Groovy provides extension methods to aid with creating temporary directories. Prior to this fix, Groovy's impleme

Apache Groovy provides extension methods to aid with creating temporary directories.

Users not using the extension methods mentioned in the advisory are not affected, but may wish to read the advisory for further details.
