      Creating my first pipeline build, trying to upload output to S3. Getting a SecurityException: Rejected: java.lang.String$CaseInsensitiveComparator

      Cause in my configuration:

      withAWS(credentials:'aws-softwareops') {
          s3Upload acl: 'Private', bucket: 'my-bucket', file: 'my-file.zip', path: 'master'
      }

      Remove this and the build works.

      Comment out s3Upload and the build works - proving the cause is definitely s3Upload, not withAWS.

      Change the credentials key ("aws-softwareops" above) to something different, and the build fails again, proving the credentials are being picked up from Jenkins correctly.

      This is in the logs:

      Jan 18, 2018 3:06:58 PM jenkins.security.ClassFilterImpl lambda$isBlacklisted$1
      WARNING: java.lang.String$CaseInsensitiveComparator in JRE might be dangerous, so rejecting; see https://jenkins.io/redirect/class-filter/

      This doesn't work:

      -Dhudson.remoting.ClassFilter=java.lang.String$CaseInsensitiveComparator

      (there is no mention of ClassFilter in the Jenkins log at startup - should there be?)

      This is a blocking issue for me.
