What are the important changes in Java JDK 11?

By -
These are few details about the changes described below are provided in JDK 11 Release Notes.


  • The deployment stack, required for Applets and Web Start Applications, was deprecated in JDK 9 and has been removed in JDK 11.
  • Without a deployment stack, the entire section of supported browsers has been removed from the list of supported configurations of JDK 11.
  • Auto-update, which was available for JRE installations on Windows and macOS, is no longer available.
  • In Windows and macOS, installing the JDK in previous releases optionally installed a JRE. In JDK 11, this is no longer an option.
  • In this release, the JRE or Server JRE is no longer offered. Only the JDK is offered. Users can use jlink to create smaller custom runtimes.
  • JavaFX is no longer included in the JDK. It is now available as a separate download from openjfx.io.
  • Java Mission Control, which was shipped in JDK 7, 8, 9, and 10, is no longer included with the Oracle JDK. It is now a separate download.
  • Previous releases were translated into English, Japanese, and Simplified Chinese as well as French, German, Italian, Korean, Portuguese (Brazilian), Spanish, and Swedish. However, in JDK 11 and later, French, German, Italian, Korean, Portuguese (Brazilian), Spanish, and Swedish translations are no longer provided.
  • Updated packaging format for Windows has changed from tar.gz to .zip, which is more common in Windows OSs.
  • Updated package format for macOS has changed from .app to .dmg, which is more in line with the standard for macOS.

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk.

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch").build();     TransportClient client = new P
