API for reading/writing a single dataset to/from a bzip2 file. File must only contain one entry.

You must have apache commons-compress included as part of your project to load this namespace. Many projects already include commons-compress so manually including it may not be necessary for your system.

Also note that version before 1.21 have several known vulnerabilities.
