Good morning,

Mi name is Juan Antonio BreƱa 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

[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
