HelloFX not starting

[DieterHolz]

running the sample 'HelloFX' leads to this error

> Task :run FAILED Loading library prism_es2 from resource failed: java.lang.UnsatisfiedLinkError: /Users/dieter/.openjfx/cache/12.0.2/libprism_es2.dylib: dlopen(/Users/dieter/.openjfx/cache/12.0.2/libprism_es2.dylib, 1): no suitable image found. Did find: /Users/dieter/.openjfx/cache/12.0.2/libprism_es2.dylib: code signature in (/Users/dieter/.openjfx/cache/12.0.2/libprism_es2.dylib) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed. /Users/dieter/.openjfx/cache/12.0.2/libprism_es2.dylib: stat() failed with errno=38 j

What can I do?

Maybe you can try to remove the cache at /Users/dieter/.openjfx?

[DieterHolz]

I did that already. Doesn't help.

BTW: I'm using AdoptOpenJDK 11.0.4

I've found an unrelated issue but with similar error messages here. It mentions the Mac's System Integrity Protection. While it should only affect a given number of system folders, is there any chance that you have extended it to your Users folder? Do you have any kind of writing restrictions applied?

There is an option to move this cache to a different location, using System.setProperty("javafx.cachedir", "path/to/cache"); in your main method of the Application class (right before launch()).

Can you try setting a writable folder?

[DieterHolz]

csrutil disable helps. HelloFX can be started via gradlew run.

I never did anything with SIP before and I don't think I'm the only one with this problem.

Shouldn't it be fixed in OpenJFX?

[johanvos]

Can you open an issue for this on https://github.com/javafxports/openjfx ?

I had the same issue, it was related to adoptium/temurin-build#1211

Reverting openjdk version to jdk-11.0.3+7 fixes it.

[jperedadnr]

The issue is indeed related to AdoptOpenJDK, and it seems it has been already fixed. The latest prerelease works fine for me.

@DieterHolz if you can verify this, feel free to close this issue.
