Good morning,
Mi name is Juan Antonio Breña Moral, I am developing a set of Java libraries for Lego Mindstorms EV3, an ARM5 robotics device and recently, we build OpenJDK 9 with success but with OpenJDK 10, we have found some problems when we execute some Java programs.
Repository to build OpenJDK 9/10 for ARM5 Soft Float: https://github.com/ev3dev-lang-java/openjdk-ev3
To test the JVM, I am using the following repo to test the VM: https://github.com/ev3dev-lang-java/vmbenchmarks
And this is the output with the error:
robot at ev3dev:~$ java -jar benchmarks.jar -f 1 WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.openjdk.jmh.util.Utils (file:/home/robot/benchmarks.jar) to field java.io.Console.cs WARNING: Please consider reporting this to the maintainers of org.openjdk.jmh.util.Utils WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release =============== DEBUG MESSAGE: Atomic load(jlong) unsupported on this platform ================

[Too many errors, abort] Aborted
I think that in OpenJDK10 changed something in compare to OpenJDK9 in relation to ARM5 support.
Any idea?
Many thanks in advance.
Cheers
Juan Antonio
