Since public support of Java 8 has ended in Q2/2019, updates and security fixes for Java Web Start are not available without a paid support contract with Oracle. Organizations have to look for alternative deployment solutions which might require substantial migration efforts. From Java 11 on, JWS does not exist any longer and, therefore, JWS based applications cannot be used with Java versions newer than Java 8. This leads to the problem that clients that have the latest version of Java installed can no longer use JWS-based applications.

In addition, they increasingly require desktop applications to be distributed through their own private application stores. Oracle argues that vendors of the most popular desktop operating systems push for applications to be delivered in bundles together with integrated, sandboxed runtimes. “Oracle will not include Java Web Start in Java SE 11 (18.9 LTS) and later.” With the release of Java 11, which happened on September 2018, Oracle removed JWS from their JDK distributions. On the Java Client Roadmap Update it has been announced that

Although JWS was advertised as an alternative to the deprecated applet technology, the days of JWS applications are now counted. The whole story began when Java applets and almost all NPAPI plugins became obsolete and were replaced by Web-based technologies.

“Java Applet and WebStart functionality, including the Applet API, the Java plug-in, the Java Applet Viewer, JNLP and Java Web Start including the javaws tool, are all deprecated in JDK 9 and will be removed in a future release.” If your application is distributed via Java Web Start ( JWS) and you are not yet concerned by the decision Oracle made regarding Java Web Start, you might not be paying attention: JWS has been deprecated in Java 9:
