A DESCRIPTION OF THE PROBLEM :
Currently use Arm java8 from Oracle and compile Openjfx for Arm and overlay libraries for current product line. Looking to test Java9 on Arm and upgrade product line in next generation release.

Cross Compiling openJdk9 for Arm works fine

Trying to compile openJfx from http://hg.openjdk.java.net/openjfx/jfx-dev/rt
Running gradle -PCOMPILE_TARGETS=armv6hf produces swing errors even though  COMPILE_SWING is false in build.gradle.

Problem seems to be with build.gradle line 2154 which has swing tasks being disabled if COMPILE_SWING is false. This code is commented out.

/* should not be built, but needed in JMX
    tasks.all {
        if (!COMPILE_SWING) it.enabled = false
    }
   */

if I uncomment it these errors go away and the build completes.

The resulting armv6hf-modular-sdk folder created by the build is added to jdk configure script with '-with-import-modules=' option as per build instructions. 
Building the jdk now fails with java.base module FindException, are these 2 problems related?

committed.

Yes, that seems best. +1
20-04-2018
Can we tackle that in a follow-up issue? In general, there are a number of things that should be cleaned up in the platform specific buildSrc/platform.gradle I think the change in this PR is the only change in build.gradle required to make it work, and at least on desktop platforms nothing changes (as COMPILE_SWING is true for those platforms).
20-04-2018
Does "gradle test" still work if COMPILE_SWING is false? The ":systemTests" project depends on ":swing"

Somewhat related to this, I filed JDK-8195788 to track removing the dead JMX code, in case that has any bearing on uncommenting out the build logic in question.
19-01-2018
Uncommenting the commented out build logic so that the swing project is disabled if COMPILE_SWING = false seems fine to get the build of FX working. The errors in compiling the JDK are likely a different issue. Assigning this to Johan since he builds FX for linux-arm and might have an idea how best to fix this.
