I'm had implement a jenkins.branch.BranchProperty that list all available ParameterDefinition.
It normally works but when I select a ChoiceParameter I got the following Exception on save:

The RequestImpl instantiate a ChoiceParameterDefinition class and than using reflection lookup a setter @DataBoundSetter annotated for "choice" property. It takes the parameter type from method (in this unlikely case Object) and than use apache beanutils to convert the actual value "v1\n2\n3" (String) to Object. Since there are no converter registered for Object it fails.
