[native-image] Code using JavaFX fails to generate native image.

[rhencke]

When attempting to generate a native image using code that uses JavaFX, an error occurs. I can't exactly understand the root cause given the error message, but I can give the steps to reproduce it.

1. Create a file HelloWorld.java, containing the example in Example 1-1 at https://docs.oracle.com/javafx/2/get_started/hello_world.htm
2. Using the Graal toolchain (in this case, graalvm-1.0.0-rc1 from Oracle download was used, on MacOS), compile the Java file: javac HelloWorld.java
3. Run the native image compiler: native-image -cp . helloworld.HelloWorld

The following error is then shown:

Error: Processing image build request failed

If you need more information, please let me know. Thanks.

@rhencke thank you for your report. He haven't tried running JavaFX apps so far. It looks like they will need a bit more work to run on SubstrateVM.
Related issue: #403.

[tisonkun]

For cross refer #358

[cubuspl42]

Managed to make it build, but doesn't run properly: #994

[hrgdavor]

Are there any plans to look into javafx ? just wondering footprint that it would have, would it be useful to develop small desktop apps.

[cstancu]

As reported by #403 (comment) it is now possible to create native executables for JavaFX applications on Linux, MacOS and iOS. I am closing this issue, please open a new one if you run into further issues.
