Incorrect OS bitness detection

See original GitHub issue

I am running a 32-bit JVM on a 64-bit Linux machine.

$ java -version
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) Client VM (build 25.25-b02, mixed mode)
$ uname -a
Linux arteam 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46 
UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

System.getProperty("os.arch") call returns i386. But my system is 64-bit anyway, regardless of bitness of the JVM. I guess it’s not a very common combination, but some users still use it.

On a 64-bit JVM detection works quite fine.

Since the whole point of this project is to run external commands, It’s the OS bitness that really matters, not the JVM bitness, so I would suggest altering BitSize.detect() to reflect this.

I agree, but windows is just one world. On Linux you can’t even start the java 32 bit binary if you are on a 64 bit system, maybe that changed (knowledge from 2016 …).
