Hi,

The current version of Jenkins is v.2.319.2 for Redhat Openshift 3.

In order to utilize the features of the Role-based Authorization Plugin, we upgraded the existing version of Matrix-Authorization Strategy plugin from v.2.6.6 to v.2.6.7, and then fresh installed the Role-based Authorization Plugin v.3.2.0.

The installation was success without any error, and Jenkins could restart successfully after the plugin installation. However, as we successfully signed in Jenkins with any registered users, Jenkins reported an error 'Oops! A problem occurred while processing the request. Logging ID=xxxxxxxxxxxxxxx' on the landing page and logged the following Unhandled Exception event in the log.

2022-05-11 02:10:40 WARNING hudson.init.impl.InstallUncaughtExceptionHandler handleException Caught unhandled exception with ID f8704ed7-53f3-4739-b4df-010da5eec14b
java.lang.ClassCastException: class com.michelin.cio.hudson.plugins.rolestrategy.RoleBasedAuthorizationStrategy cannot be cast to class hudson.security.GlobalMatrixAuthorizationStrategy (com.michelin.cio.hudson.plugins.rolestrategy.RoleBasedAuthorizationStrategy is in unnamed module of loader jenkins.util.AntClassLoader @b1aa77c; hudson.security.GlobalMatrixAuthorizationStrategy is in unnamed module of loader jenkins.util.AntClassLoader @2bf821c) 

We could still able to access the 'Dashborad' even such exception event occurred, and run the pipeline scripts properly.
