f:repeatableProperty documentation talks about including f:repeatableDeleteButton, but then fails to actually call d:invokeBody.
While you could put the delete button at the end of the nested config.jelly, this is ugly since it prevents reuse;
better to specify the delete button in the form using f:repeatableProperty.
f:repeatableHeteroProperty already inserted a delete button automatically, so its documentation was incorrect.

1. Use AtomicFileWriter on the hypothesis that an exception during save() caused truncation.
2. Improve logging from the cleanup thread since that may be related to the root cause.
3. Regardless of the cause, recover more gracefully by deleting any truncated file rather than throwing the error up.

Fixing copy-paste error

[FIXED JENKINS-19171] Identify user agent for Internet Explorer 11.

Added a test case in an attempt to isolate the root cause of the problem, but this one works as expected. Hmm.

Merge remote-tracking branch 'origin/pr/934'

Jenkins with folders A job A/j
a top-level view to recurse into subfolders and include all available jobs and folders (so A and A/j)
=> builds for A/j are included twice, as view.builds iterate on its items, so get A/j + builds from A.

Simplify assertions since webClient#getPage already throws an exception

Replaced tabs by spaces

Should follow this statement:
"Called after a job has its configuration updated."

Should follow this statement:
"Called after a job has its configuration updated."

JENKINS-17108. This solves the problem with ItemListner.onUpdated not being called if the project was disabled/enabled by pushing the button on the project page. Also solved the problem with ItemListener.onUpdated not getting called if the project description was updated using the edit description on the project page.

in case of erroneous http status code.
