JavaFx 11 on RHEL 6

[Kevin Rushforth]

The main thing we need the newer Glibc for was the native gstreamer 
stack. Our solution for FX 8, which still supports RHEL 6, was to build 
glib on linux and link it into the runtime. You might be able to look at 
the media Makefiles for FX 8 at 
https://hg.openjdk.java.net/openjfx/8u-dev/rt , specifically, the FX 8 
build changes for JDK-8199527. There might also be some changes needed 
for building the glass GTK2 code, which were uncovered when we recently 
backported GTK3 to FX 8. I won't be able to answer any specific 
questions you might have, but maybe that will point you in the right 
direction.

I presume altering build scripts would not be a problem for us, but if there are any significant, possibly architectural, changes in the software itself (that require something RHEL 7 exclusive), then perhaps we might be barking up the wrong tree. Can you think of anything? Off the top of your head.

We're now trying to switch (from Oracle Java 8) to use java 11 with openjdk and openjfx. It all seems fine except if I want to run our application on Linux RHEL 6. Then I get errors about unsatisfied links to do with glibc version, while trying to initialise the graphics. We've reached out to our customers and those that run linux are pretty much all still on RHEL 6 and have no plans to move. I've looked about on the internet and can't find any solution to this problem. Are there any plans for addressing this in future versions of openjfx?
