Java (Desktop)
Roadmap

Karakun DevHub_
Oracle Java Desktop Roadmap
• Oracle announced a roadmap for Java on desktop
last year (in March 2018)
https://bit.ly/2JiwELG

Karakun DevHub_
"The application development market has shifted dramatically
over the past decade…
To address these requirements, Oracle proposed to shift Java
to a strict time-based release model, …
These changes create an opportunity to simplify and focus the
client roadmap going forward."

"Swing and AWT will continue to be supported on
Java SE 8 through at least March 2025, and on Java
SE 11 (18.9 LTS) through at least September 2026."

Karakun DevHub_
"Oracle will continue to commercially support Java
Web Start on Java SE 8 for commercial use, or when
used in conjunction with Oracle products that have a
Web Start dependency, through at least March 2025"

Karakun DevHub_
"JavaFX new ﬁxes will continue to be supported on
Java SE 8 through March 2022 and removed from
Java SE 11."

Karakun DevHub_
• Swing will be supported in future (commercial)
Java 8 and 11 updates
• We have no idea what will happen to Swing in
future Java LTS versions

Karakun DevHub_
• WebStart will be supported in future (commercial)
Java 8 updates
• WebStart is removed in Java 11

Karakun DevHub_
• JavaFX will be supported in future commercial Java
8 updates
• JavaFX is removed in Java 11

Karakun DevHub_
"Oracle has begun conversations with interested
parties in the Java ecosystem on the stewardship of
JavaFX, Swing and AWT beyond the above
referenced timeframes."

@HendrikEbbers
Java is not "only Oracle"
anymore

Karakun DevHub_
Swing & AWT
• Swing and AWT won't used for new projects
anymore
• Stable APIs and no new features needed

Karakun DevHub_
Swing & AWT
• But: the private API will change from time to time
• Replace native rendering engine based on os
changes
• Toolkits need support in future
• Who will do that???

Java Packaging Tool

Karakun DevHub_
jpackage
• Build native executables for your application
• Supports jlink
• You can use it today (with hacks)
• Beta in Java 14 & 15

Karakun DevHub_
JavaFX today
• Such issues must be targeted in future and LTS
versions
• Currently companies provides LTS support for
JavaFX 8 and 11

@HendrikEbbers

JavaFX 8 @ AdoptOpenJDK
• We got often asked why we do not add JavaFX to
the Java 8 binaries
• We only want to provide secure / up-to-date
binaries
• There is not open source JavaFX 8 development

Karakun DevHub_
JavaFX 11+
• When using Java(FX) 11+ you should add JavaFX as
a dependency
• Using a JVM with integrated JavaFX is not the
preferred solution

Karakun DevHub_
JavaFX 11+
• Maybe Oracle is only interested in JavaFX until the
LTS support of Java 8 ends
• Today Oracle needs to contribute to JavaFX (based
on the commercial support for Java 8)

Karakun DevHub_
JavaFX 14+
• There is a good chance that JavaFX 14 will run with
Java 11
• No one knows if JavaFX 15 will still be compatible

Karakun DevHub_
JavaFX 14+
• If you want to stay on Java 11 you will need to pay
in future

JavaFX 14+
• Best: buy commercial support today
• … no downgrade from JavaFX 14 to 11 needed in
future
• … your money will help to ﬁx issues today

@HendrikEbbers
If companies do not care 
JavaFX will go away!

Karakun DevHub_
Homework
• Is my company interested in the future of JavaFX?
• Is my company interested in the future of Java
Desktop?
