JavaFX for Windows 32-bit

[Robert Lichtenberger]

In order to upgrade our JavaFX-based products to Java/JavaFX 12 I need a
build of JavaFX for Windows 32-bit.

The good people at AdoptOpenJDK kindly have provided Java 12 for win32
already, but there is only one "Windows"-Download at Gluon which I suppose
will be for Windows 64-bit.

So I guess I'll just have to build it myself. According to
https://wiki.openjdk.java.net/display/OpenJFX/Building+OpenJFX this should
be possible, since "Note also that on Windows, the version of the JDK you
have set as JDK_HOME will determine whether you build 32 or 64 bit
binaries.".

What is the mid-to long-term perspective of JavaFX on win32? Will it be
buildable for the next few years or should I prepared for breaking changes
that will make it unusuable for win32?

Any hints / opinions / pointers welcome,
