[JENKINS-56362] When the Jenkins server is restarted, any DEFAULT password parameters set in jobs are getting clobbered.

All of our jobs that require a password in the job execution (i.e. a codesign keychain password) we set it as a Default Password Parameter in the job config. Recently after a Jenkins update 2.150.1 to 2.150.3 the passwords appear to be getting overwritten by what appears to be an encoded string instead. For example, I print the parameter in a shell in the job config. It's supposed to be a clear text password, but instead, it's something like this:  

echo '{AQAAABAAAAAQu+DPUyCuv/3iI87yPZNs+tar+8vNJqHDr+uTQrlE8if=}

I have a question, is the $JENKINS_HOME/secrets folder involved?
