---------------------------------------

             Summary: groovy json -  Unable to load FastStringService with java 11 http client
                 Key: GROOVY-9802
                 URL: https://issues.apache.org/jira/browse/GROOVY-9802
             Project: Groovy
          Issue Type: Bug

    Affects Versions: 3.0.6
         Environment: Groovy Version: 3.0.6 JVM: 11.0.9 Vendor: Amazon.com Inc. OS: Linux

            Reporter: Matias Bjarland


The following code: 
{code:java}
import groovy.json.*
import java.net.http.*
import static java.net.http.HttpResponse.*

def req = HttpRequest.newBuilder()
      .uri(URI.create('https://jsonplaceholder.typicode.com/todos/1'))
      .build()

def parser = new JsonSlurper()
// parser.parseText('{}') // <--- commenting out this line will make the code break 

def res = HttpClient.newHttpClient().sendAsync(req, BodyHandlers.ofString())
       .thenApply(r -> r.body())
       .thenApply(parser::parseText)
       .join()

println "response: $res"

{code}
when run, will break with the following exception:

commenting in the indicated line will make the code work. 

I assume this is caused by the fact that the `thenApply` block of code is run from a different (pooled) thread and from a different classloader context. I get this, but in my mind having this simple example break is not great ergonomics for groovy.
