Hi Robert: I'm testing it and getting *consistently* the same exception with this config:
Apache Maven 3.6.0 (97c98ec64a1fdfee7767ce5ffb20918da4f719f3; 2018-10-24T15:41:47-03:00) Maven home: C:\productos\apache-maven-3.6.0\bin\.. Java version: 1.7.0_80, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk1.7.0_80\jre Default locale: es_AR, platform encoding: Cp1252 OS name: "windows 8.1", version: "6.3", arch: "amd64", family: "windows" (actually it is a win 10 but it fails to recognze it). It works OK when remote debugging with mvnDebug. Don't know why throws a NoSuchElementException when trying to remove an element on a non empty LinkedList...my best guess is that it is some sort of bug in the hotspot optimization of the JVM. Which Java 7 specific update is running on Jenkins?
