Hi Kevin,

Thanks for shedding some light on this.

I looked into javafx-graphics-16-win.jar and I can see that vcruntime140.dll and \
vcruntime140_1.dll are indeed both present.

It is not the case however in javafx.graphics.jmod (or any of the jmod files) that \
are used with jlink, so I suppose this is the root cause for my problem, rather than \
an issue with loading them.

As a side note, "javafx.graphics.jmod" does not contain any of the VS \
libraries(vcruntime140, msvcp140, api-ms-win-*, etc...) whereas the jar contain them \
all. I suspect this has not caused any issues so far because OpenJDK already bundles \
them anyway (with the exception of vcruntime140_1, which is why the issue is now \
showing).

-- Fred

Yes, JavaFX 16 uses VS 2019, but those libraries should be distributed 
as part of the JavaFX 16 bundle. It's possible we have a bug in 
NaativeLibLoader where they are not getting loaded.
