Source files for Liberica's JavaFX

Question

I want to see JavaFX types' javadocs in IntelliJ IDEA.

To do that, I need to download the sources and specify the zip in the sourcepath (Project Structure - SDKs - Sourcepath). I did it.

However, once I navigate to any JavaFX type, the IDE says:

Library source does not match the bytecode for class [class name]

It seems the sources are for a different version than the one bundled in the Liberica JDK 8 that we use (jre\lib\ext\jfxrt.jar).

I tried the following versions: 8, 2.1, 2.2. The message persists.

Where do I find the sources for the bundled JavaFX?

Download JDK And Source Files

• Select Full JDK
