How to whitelist Build Flow Plugin

[Jagjeet Singh]

after upgrading to Jenkins 2.213 I'm seeing issues with build record serialisation. Build records are not being saved and are lost when the service is restarted. Here is error I am seeing.

SEVERE: Failed to save build record

I found your conversation on https://groups.google.com/forum/m/#!msg/jenkinsci-users/5ggNkmjewng/K7J_lLMBAgAJ

There it is written as Suppress the entire whitelist by using "-Djenkins.security.ClassFilterImpl.SUPPRESS_WHITELIST=true"

I had run the below command on my windows Jenkin path:
java -Djenkins.security.ClassFilterImpl.SUPPRESS_WHITELIST=true -jar jenkins.war ...

It has turned my existing Jenkins server to newly installed one. I have to configure everything from fresh. All the jobs are missing.

Also is there any other way by which we can whitelist the build flow plug-in?

PS: My Jenkins Project's is on Linux. So looking for solution which can be applied on Linux server.
