Steps to Reproduce

This error occurs because Jenkins has removed the obsolete Apache Commons Lang 2 library (org.apache.commons.lang.*) from the core system. Meanwhile, the Jenkins Templating Engine (JTE) plugin attempts to use the legacy StringEscapeUtils class (which has since been replaced in recent libraries by Commons Text or Commons Lang 3).
Thus any pipeline job relying on the template engine may be concerned by this issue.
