Uncaught ClassCastException in groovy

Jakub Cieplinski

I'm trying to write wrappers on Jira API functions with exception handling.

 

void setField(String field, value, MutableIssue issue = this.issue) {

def cfo = cfm.getCustomFieldObject(field)

try {
    issue.setCustomFieldValue(cfo, value)

} catch (e) {
    LOG.error('Test')
}

I purposefully try to insert wrong type of value into given customfield to trigger an exception. And it does

Caught exception while attempting to perform action 181 from workflow 1081660 on issue 'xxx'

java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.util.Collection (java.lang.Integer and java.util.Collection are in module java.base of loader 'bootstrap')

However it is not being caught by the try-catch block. Why is that? Code is in groovy

Hi @Jakub Cieplinski ,

 

based on the error it seems that you are trying to put and integer to a collection custom field (it could be a selectlist, versions, components field).

You should set field value based on the field type (double for Numeric field, String for text field, Option for single selectlist, Collection<Option> for multiselect, Collection<Version> for version field and so on).

 

Hope this helps,

Fabio
