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@ev3dev:~$ java -jar benchmarks.jar -f 1

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
