In the Bitbucket Builds page, when clicking on "Authorize actions" on any build and confirming the redirection, the OAuth error "signature_invalid" is thrown:

The same error message is logged in the Jenkins log.

The error persists after recreating the application link on Bitbucket and the OAuth consumer configuration on Jenkins.

We started seeing the error after upgrading Jenkins to 2.524. (The Bitbucket Server plugin was already at version 4.2.0)
