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.


home/dell/Documents/IwOpenJdk9/src/openjfx/rt/modules/javafx.swing/src/main/java/module-info.java:36: \
error: file should be on source path, or on patch path for module module javafx.swing \
{

/home/dell/Documents/IwOpenJdk9/src/openjfx/rt/modules/javafx.swing/src/main/java/com/sun/javafx/embed/swing/SwingNodeHelper.java:26: \
error: file should be on source path, or on patch path for module package \
com.sun.javafx.embed.swing;....

Problem seems to be with build.gradle line 2154 which has swing tasks being disabled \
if COMPILE_SWING is false. However 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?


Note: Recompile with -Xlint:unchecked for details.
