          Hello,

          The issue has been caused by Trac plugin:

          at hudson.plugins.trac.TracProjectProperty$DescriptorImpl.newInstance(TracProjectProperty.java:67)

          I've re-assigned the issue

          Do you recommend to turn off this plugin?

          It depends on your needs.
          If you don't use Trac plugin, it could be an applicable workaround for you

          We are receiving the same error after upgrading to 1.536, our fix was to downgrade to 1.535 as we do not have the Trac plugin installed. So I do not think the problem is limited to that plugin.

          1. Plugin was disabled and I can save job configuration.
          2. Previously, I have faced a similar problem. I think that the problem is not related to the plugin Trac.

          I also get same error and Just remove the trac plug-in. The error was disappear. I think the development team will get rid of this error sooner. Good luck! Happy development and deployment. Thanks.
