I am working with Jenkins 1.615 and Coverity Plugin 1.6.0
I have installed the Coverity 7.7.0 in same server where I have Jenkins 1.615

I have configured the Coverity with Jenkins by updating
1. Jenkins->Manage Jenkins>Configure System->Coverity Static Analysis location and checked connection.
2. Jenkins->Manage Jenkins>Configure System->Coverity Connect instances and checked the connection. Both are valid.

I have created a freestyle job and added Coverity in post build action. I tried adding a stream for analysis. I am able to see the "coverity connect instance name" in dropdown but not able to see the dropdown values for project,stream and language.

I saved it and when I reopen the configure page for the freestyle job page didnt respond. All other options like "Back to Dashboard" "Status" etc are working fine. Please find the attachment for error message in Chrome.

Error Message from logs is as below:
