EasySSO & Jespa 1.2.11 Incompatibility
Incident Report for TechTime Initiative Group
New versions for all EasySSO products have been released and are available for download via the Marketplace as 4.5.14, except for Jira 8.22.2 which requires EasySSO

As per release notes for IOPLEX Jespa 1.2.11 (https://ioplex.com/jespa_release.html) their distribution now includes two .jar files – one for Tomcat 9.x and one for Tomcat 10.x

It seems EasySSO classloader gets confused and loads the wrong .jar incompatible with the Tomcat version used by Atlassian applications – we are working on an urgent fix in 4.5.x branch to load the correct file.
