MarsSeed [1] filed a deletion request for crawljax [2]: Not useful to keep this abandoned Java package on AUR. Submitter maintained it between 2013 and 2019. Only they commented, and the package has only 1 vote. This is a developer's automated testing application, most useful in CI. Upstream's releases can be easily acquired from Maven Central repository, either for local or server deployment.
