Possible incompatibility with JavaFx

Not sure where this problem lies, but I’ve been experiencing a core dump crash somewhere in libfreetype when JavaFx is initialized before rendering text using canvas drawString.

Ubuntu 18.04
openjdk version "12.0.1" 2019-04-16
OpenJDK Runtime Environment Zulu12.2+3-CA (build 12.0.1+12)
OpenJDK 64-Bit Server VM Zulu12.2+3-CA (build 12.0.1+12, mixed mode, sharing)

I am trying to use skija’s text rendering functionality. However, when JavaFx is initialized before trying to render with skija, the whole repl crashes with a core dump somewhere in libfreetype.

When I do the skija text rendering first, and then initialize JavaFx, things seem to work.

I have added a demo project here: https://github.com/mjmeintjes/skija-cljfx-crash-demo

If I execute (Platform/startup #(Platform/setImplicitExit false)) before (create-image-with-text), then the JVM crashes due to a crash in native code, somewhere in libfreetype.

However, if I execute (create-image-with-text) first, then I can run the startup code and then (create-image-with-text) can successfully run.

Thanks, 0.92.30 seems to have fixed this issue for me as well.

Ok, I think we fixed it in 0.92.30. The core of the problem was Freetype, which was initialized both statically (us) and dynamically (JFX). I switched it to dynamic for Linux and the problem seems to be gone. Works on my Ubuntu 20.04. Please let me know if it bugs you again.
