Overview of jBallerina 1.1.1

Ballerina 1.1.1 is a patch release iteration of its previous 1.1.0 release, which introduces the below functionalities. Also, this release addresses a few bug fixes and improvements.

You can use the inbuilt updating capability (introduced in jBallerina 1.1.0) to update to jBallerina 1.1.1 as follows.

For existing users:

If you are already using jBallerina version 1.1.0, you can directly update your distribution to jBallerina 1.1.1 by executing the below command:

ballerina dist update

However, you need to execute the below commands if you have installed:

• jBallerina 1.1.0 but switched to use a previous version: ballerina dist pull jballerina-1.1.1
• jBallerina 1.1.1 via the installers: ballerina dist use jballerina-1.1.1
• a jBallerina version below 1.1.0: install via the installers

For new users:

If you have not installed jBallerina, then download the installers to install.

Language Specification Deviation Fixes

Previously, the implementation initialized an object field’s default value in the __init() function of the object, which caused the default values to be set to the field even when the __init() method was called explicitly.

For example, the below sample prints “foo” as the value of f.s since the default value “foo” was set as the value of f.s whenever the __init() method was called.

import ballerina/io;
 
type Foo object {
  
   string s = "foo";
 
   function __init() {       
   }
 
   function reInit() {
       self.__init();
   }
};
 
public function main() {
   Foo f = new();
 
   // Update field `s`.
   f.s = "bar";
 
   f.reInit();
   io:println(f.s);
}

This is fixed in 1.1.1 so that now this sample prints “bar”.
