$Subject

Note: This is not reproducible with Ballerina SwanLake Update 11 or higher versions

Steps to Reproduce

Run the following Ballerina service:

import ballerina/http;

service / on new http:Listener(9090) {

    resource function get hello/[string name]() returns string {
        return "Hello, " + name;
    }
}

Try to invoke with the below cURL request:

curl 'http://localhost:9090/hello/123/456' --header 'Authorization: Bearer xxxxx' -v

Version

Ballerina - 2201.8.x, 2201.9.x and 2201.10.x

Environment Details (with versions)

No response

This was due to a blocking call made from dispatcher to decode the JWT token which is added to the request context object[1]. This somehow blocked the entire strand group and the response was not able to sent out.

Had a chat with @warunalakshitha, and since the JwtDecoder class and the decode method are isolated, we should use invokeMethodAsyncConcurrently which will be executed in a new strand group other than blocking the current group

The fix has been added to the following versions:

• Ballerina SwanLake Update 8(2201.8.x): 2.10.24
• Ballerina SwanLake Update 9(2201.9.x): 2.11.12
• Ballerina SwanLake Update 10(2201.10.x): 2.12.11
