Re: Running JavaFX-11 applications from within Eclipse fails

[Kevin Rushforth]

Renaming the native libraries in JavaFX would probably solve this, but that
seems the wrong solution to me.

Yes, it seems like a workaround rather than a fix...

Hi Tom,

Nice workaround, but what do you think needs to be done to fix it? Can the
java.library.path somehow be changed in a plugin or so?

Hi,

I just wanted to make you aware that if you run a JavaFX-11 application
from within Eclipse it is very likely that you'll get an error like this.

Scary right! The reason is that JavaFX-11 is loading the wrong glass.dll
because Eclipse sets a java.library.path who also contains the
JVM-Directories used to launch your Eclipse IDE.

The simple work-around is to add
-Djava.library.path=C:/go-out-of-my-way-eclipse in your launch
configuration.

Small tiny question on the side: Wouldn't it make sense to version our
.dlls somehow to match the release eg glass-11.dll?
