I have created a freestyle project.

Our requirement is: based on a parameter selection (single select), the other parameter values (checkbox values) should render.

I have used Active Choices Parameter for Single Select. Name is "Test" for example and 

Active Choices Reactive Parameter for Check Boxes (and mentioned the above Param's name in Referenced Parameter) Name is "Temp". And for this Referenced parameters is set to "Test"

This was working absolutely fine from last one year. However after upgrading Jenkins along with the Plugins due to Security issues, this started to not work as expected.

For Active Choices Reactive Parameter: It is throwing an error  saying: 'groovy.lang.MissingPropertyException: No such property: Test for class: groovy.lang.binding'

(Attested the screenshots for reference)

Could you please help me with this issue. As it is currently blocking the execution of Jobs for Bug testing.

Note: Observing the same issue with "Active Choices Reactive Reference Parameter"
