[FIXED JENKINS-33549] Specify on the logger the job which cannot create a new build

[FIXED JENKINS-37561, CID-1205051] - Prevent resource leak in AntClassLoader#findClassInComponents() (#2517)

It has been originally reported by Coverity in https://scan5.coverity.com/reports.htm#v36021/p10292/fileInstanceId=97573616&defectInstanceId=28155759&mergedDefectId=1205051. It happens on Exceptional paths only, but actually I see 31 runaway handlers on my jenkins-2.18 instance (maybe happens due to plugin dynamic load failure)

The issue happens, because finally block is misplaced. It handles only the last stream in this cycle

* [JENKINS-37332] - Improve diagnostics of non-closed streams during reading of the manifests in PluginManager

* [JENKINS-37332] - Leakless processing of JarUrlConnection during Manifest parsing

* [JENKINS-37332] - Also implement leak-safe method for retrieving file modification date

* [JENKINS-37332] - Add spotcheck methods for manifest file access + Javadoc

* [JENKINS-37332] - Also test multi-line and empty attributes in the test

Provide a sensible default implementation of configure.

[JENKINS-37315] Stop A/B testing JNLP3

[FIXED JENKINS-37189] Only append `?uctest` to http/https update center URLs

- A pure unit tests will suffice

[JENKINS-37098] don’t rely on ReopenableFileOutputStream

* Added translation

* Corrected translation

- Also fixes to append `&uctest` if the update center URL already contains a query fragment

ReopenableFileOutputStream introduces file-leaks (detected on windows) when channel onClose writes on already closed log, and breaks when computer tries to delete the slave’s log directory.

[JENKINS-36717] - FindBugs cleanup

'{0}' is the literal string {0} in a message format - if you want to quote
the parameter then you need to use double single quotes ''{0}''
