Cross-compile openjdk for aarch64 ARM architecture

[Mohammed Bey Ahmed Khernache]

Hello,
I am trying to cross-compile openjdk for my board (Snapdragon 810) which
has aarch64 ARM architecture, under Android OS.
I am following the following web page:
http://openjdk.java.net/projects/mobile/android.html

I cross-compiled libffi and libfreetype.

1) the link given to clone openjdk from Github is no longer available. Is
there someone who has a copy or knows another link?
2) I tried to dowlonad jdk9, but when I reach the step of compilation "make
images" in the web page above,
The configure command options:
-------------------------------------------------------------------------------------------------
./configure  --enable-option-checking=fatal
--openjdk-target=aarch64-oe-linux  --disable-warnings-as-errors
--enable-headless-only  --with-jdk-variant=normal
--with-jvm-variants=zero  --with-debug-level=release
--with-devkit=$ANDROID_DEVKIT  --with-libffi-include=$LIBFFI_DIR/include
--with-libffi-lib=/root/jdk9mobile/libffi-3.2.1/arm-unknown-linux-androideabi/lib
 --with-freetype-lib=$FREETYPE_DIR/lib
--with-freetype-include=$FREETYPE_DIR/include/freetype2
-------------------------------------------------------------------------------------------------
I got compilation errors!

Is there any solution to this error?
Or, is there any other solution to cross-compile openjdk for aarch64 ARM
architecture?

Thank you in advance.
