This is my script (not a pipeline  - just system groovy script):

params = [new StringParameterValue ('GIT_PUSH_USER','builder'), new StringParameterValue ("SHA1",'9df4d51934c3f39663c5dbc1e08c09775b45c61f'),
, new BooleanParameterValue('TEST_ONLY_CHANGED',false)]

parmAction = new ParametersAction(params)

Causes failure with:

org.codehaus.groovy.runtime.typehandling.GroovyCastException
: Cannot cast object '[(StringParameterValue) GIT_PUSH_USER='builder', (StringParameterValue) SHA1='9df4d51934c3f39663c5dbc1e08c09775b45c61f' (BooleanParameterValue) TEST_ONLY_CHANGED='false']' with class 'java.util.ArrayList' to class 'hudson.model.ParameterValue' due to: groovy.lang.GroovyRuntimeException: Could not find matching constructor for: hudson.model.ParameterValue(hudson.model.StringParameterValue, hudson.model.StringParameterValue,hudson.model.BooleanParameterValue)
