arduino.exe closes shortly after execution.

Running arduino_debug.exe:

java.lang.Error:

There is an incompatible JNA native library installed on this system
[the beginning of my PATH]
To resolve this issue you may do one of the following:
 - remove or uninstall the offending library
 - set the system property jna.nosys=true
 - set jna.boot.library.path to include the path to the version of the
   jnidispatch library included with the JNA jar file you are using

I took a look at #1948 and #2301 but could not figure out how to set the system property described.

Hi @jczimm , the problem is indeed #1948, which was fixed by #2301 but reintroduced by the twin commits f6546ae and 98eb1a9

@cmaglie , can we safely reapply e7fc9a1 ?

@jczimm , I just opened a PR here #5097.
ArduinoBot should build it and place the compiled packages as a comment. Could you test the Windows one and report if it solved your problem? Thanks

@facchinm , this solved the problem! Thanks!
