I did find a solution, though not an explanation of why my original code
didn't work. After viewing the source code for createUpdated, I wrote
Groovy code to perform the same steps. Here's my working function to
update the Jenkins parameters for a job while it is running. Existing
parameters will be updated, and new parameters will be added to the job.
import hudson.model.*
def setBuildParameters(parmMap) {
def npl = new ArrayList<StringParameterValue>()
for (k in parmMap.keySet()) {
npl.add(new StringParameterValue(k, parmMap.get(k)))
}
def newPa = null
def oldPa = build.getAction(ParametersAction.class)
if (oldPa != null) {
for (oldp in oldPa) {
if (! parmMap.containsKey(oldp.name)) { // if oldp was not
overridden by the new list
npl.add(oldp) // then add it to the
new list
}
}
build.actions.remove(oldPa)
}
newPa = new ParametersAction(npl)
build.actions.add(newPa)
}
Notes: This code was run as a System Groovy Script build step. As
written it only covers String parameters.

Groovy script build step in Jenkins 1.509.4 on Win 7, with parameter
INSTALL_HOME defined in the job with no default:
import hudson.model.*

npl.add(new StringParameterValue("INSTALL_HOME",
"/home/test/install/my_install"));

} else {
newPa = new ParametersAction(npl);
}

This does not make sense. It says right in the error message that I'm
calling createUpdated with argument of type ArrayList, containing
values of type StringParameterValue, and the declaration of method
createUpdated is:
public ParametersAction createUpdated(Collection<? extends ParameterValue>
overrides)
Any idea what's going on?
Thanks,
Eric
