First, create a pipeline job with this pipeline that contains a class definition:
class Data implements Serializable { final String string Data(final String string) { this.string = Objects.requireNonNull(string) } boolean equals(final other) { if (this.is(other)) { return true } if (getClass() != other.class) { return false } final Data that = (Data) other return string == that.string } int hashCode() { return string.hashCode() } } final d1 = new Data('a') final d2 = new Data('b') final d3 = new Data('c') final s1 = 'a' final s2 = 'b' final s3 = 'c' final s0 = [s1, s2, s3] echo "s1: ${s0.getClass()}" final ss1 = [s1, s2, s3].toSet() echo "ss1: ${ss1.getClass()}" final Set<String> ss2 = [s1, s2, s3] echo "ss2: ${ss2.getClass()}" final Set<String> ss3 = [s1, s2, s3].toSet() echo "ss3: ${ss3.getClass()}" final ss4 = [s1, s2, s3] as Set<String> echo "ss4: ${ss4.getClass()}" final Set<String> ss5 = [s1, s2, s3] as Set<String> echo "ss5: ${ss5.getClass()}" // Is there some issue with hashCodes? // Maps seem to also be affected? //final m1 = [:] //m1[d1] = s1 //echo "Map: ${m1.getClass()}" //echo "${m1.size()}" //echo "Map keys: ${m1.keySet().getClass()}" //echo "Map first key: ${m1.keySet().toList()[0].getClass()}" final d0 = [d1, d2, d3] echo "d0: ${s0.getClass()}" final ds1 = [d1, d2, d3].toSet() echo "ds1: ${ds1.getClass()}" // Fails with: // com.cloudbees.groovy.cps.impl.CpsCallableInvocation //final Set<Data> ds2 = [d1, d2, d3] //echo "ds2: ${ds2.getClass()}" // Fails with: // hudson.remoting.ProxyException: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '97' with class 'java.lang.Integer' to class 'java.util.Set' //final Set<Data> ds3 = [d1, d2, d3].toSet() //echo "ds3: ${ds3.getClass()}" // Fails with: // hudson.remoting.ProxyException: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '97' with class 'java.lang.Integer' to class 'java.util.Set' //final ds4 = [d1, d2, d3] as Set<Data> //echo "ds4: ${ds4.getClass()}" // Fails with: // hudson.remoting.ProxyException: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '97' with class 'java.lang.Integer' to class 'java.util.Set\' //final Set<Data> ds5 = [d1, d2, d3] as Set<Data> //echo "ds5: ${ds5.getClass()}"
Run once, and approve the hashCode() signature since it is not in default whitelist right now:
Uncomment any of the lines under the cases above, build again, and see failure and confusing types. For example, uncommenting the ds3 example above results in this:
