Oracle announced a language server tool for Java developers using Visual Studio Code to provide language-specific 'smarts' in the super-popular, open source-based, cross-platform code editor.

Newer versions of Java now require all JAR files to be signed with a valid code-signing key, and starting with Java 7 Update 51, unsigned or self-signed applications are blocked from running.

Oracle has released the Oracle Java Platform extension for Visual Studio Code, bringing full-featured Java development for Maven and Gradle projects to Microsoft’s popular code editor.
