[jira] [Created] (GROOVY-11748) Groovy JsonSlurper returns null

Ramesh Venkitaswaran created GROOVY-11748:
---------------------------------------------

             Summary: Groovy JsonSlurper returns null
                 Key: GROOVY-11748
                 URL: https://issues.apache.org/jira/browse/GROOVY-11748
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 5.0.0
            Reporter: Ramesh Venkitaswaran


When I run my test script against Groovy 5.0.0, this returns null, whereas the same script runs correctly against Groovy 4.0.28 
{code:groovy}
import groovy.json.*

def url = 'https://api.weather.gov/gridpoints/TOP/31,80/forecast'
def response = new URL(url).text
def weather = new JsonSlurper().parseText(response)
assert weather.properties.periods != null
{code}
In 5.0.0, this returns (partially reproduced), whereas in 4.0.28 it correctly returns the map of the parsed json.

Exception thrown

Assertion failed:
