Description

Retrieving http://localhost:8085/rest/api/latest/result/TEST-TEST.json?expand=results.result.vcsRevisions.vcsRevision.changes.change fails with NullPointerException when it contains a build referencing a commit and the corresponding repository has been deleted. However, displaying the build, commit etc. in the web interface seems to work.

java.lang.NullPointerException

Reproduce the issue

• Create a new Plan (e.g. TEST) using a Git or Subversion repository (Job with only checkout task suffices)
• Trigger the build of the plan manually
• Commit and push a change to the repository
• Let Bamboo build the plan with the change (using Repository polling trigger)
• Modify the plan: remove repository
• Might be optional: add the same repository again
• Open REST URL http://localhost:8085/rest/api/latest/result/TEST-TEST.json?expand=results.result.vcsRevisions.vcsRevision.changes.change (assuming both project and job have key "TEST")
