JEP 153: Launch JavaFX Applications
|Discussion||core dash libs dash dev at openjdk dot java dot net|
java command-line launcher to launch JavaFX applications.
In addition to supporting the launching of Java classes through their
main methods, and of executable JARs through their
manifest headers, the
java launcher should also support the direct
launching of JavaFX application JARs.
The feature will not enhance the launcher to:
- Download any components from the network,
- Replace existing RIA deployment tools, or
- Launch modularized JavaFX applications.
This feature should not adversely affect the startup performance of non-JavaFX applications and tools.
JavaFX applications are currently launched via the
java launcher by
bundling the JavaFX initialization logic as the main class in the
application’s JAR file. In the event that this logic is erroneous,
having the initialization logic embedded in the deployed JARs makes it
difficult to distribute fixes without redistributing all applications.
By moving the initialization logic into the
java launcher itself, this
problem can be eliminated.
Mark JavaFX application JARs so that the launcher can recognize them and then use JavaFX-specific logic to launch them. One way to do this would be to define a new JAR-manifest header.
Existing startup performance tests will be run.
This feature depends on upon JavaFX being integrated into the JDK.
