@v1v In light of recent PR's merged, would it be possible for you to review and resolve the conflicts in the following files?:

• src/test/java/hudson/plugins/build_timeout/BuildTimeoutWrapperIntegrationTest.java
• src/test/java/hudson/plugins/build_timeout/operations/AbortAndRestartOperationTest.java

[krisstern]

Code in pull request is too buggy even after initial attempts to fix. Mostly NullPointerExceptions that cannot be handled simply.

Closing pull request as stale.
