Doesn't work with ACME arietta board / ARM AT91SAM9G25

The error message is:

A fatal error has been detected by the Java Runtime Environment:

SIGILL (0x4) at pc=0xb000f828, pid=664, tid=0xafd2e460

If you would like to submit a bug report, please visit: http://bugreport.java.com/bugreport/crash.jsp The crash happened outside the Java Virtual Machine in native code. See problematic frame for where to report the bug.

The system is composed with:

• Arietta board from acme: https://www.acmesystems.it/arietta
• CPU AT91SAM9G25: https://www.microchip.com/wwwproducts/en/AT91SAM9G25
• The linux system was built with buildroot (board model included into official buildroot)
• Buildroot LT 2019-02.6
• Kernel linux 4.19

I manage to make it working by using the ARM 5 / linux .so library from the .jar file. I unzip jar file and copy the arm5 .so file into the arm6 .so location.

So the jserialcomm had chosen the bad .so binary to deploy.

My /proc/cpuinfo gives the following:

processor : 0 model name : ARM926EJ-S rev 5 (v5l) BogoMIPS : 198.76 Features : swp half thumb fastmult edsp java CPU implementer : 0x41 CPU architecture: 5TEJ CPU variant : 0x0 CPU part : 0x926 CPU revision : 5

Hardware : Atmel AT91SAM9 Revision : 0000 Serial : 0000000000000000

Is it possible to add this CPU to the main class loading processus ?

Sorry for the delay! Please try the following version and see if it works for you:

This change was actually released as part of the new official library version (2.6.0). Please try the newest version and see if that works for you!

Thank you. Now it works. I included the 2.6.2 version.
