File Descriptor leaks when parsing Groovy Class files in Stapler (Groovy UI)

    • jenkins-2.7.3
      staple 1.243 (default for this version)

      It happens due to the issue similar to JENKINS-37041. JarUrlConnection is not being processed correctly.
      Potential impact is low since we are not going to replace the files on the flight
