JNA error

[Jaxan]

One of the students found this error while running ALEX:

The word could not be executed. java.lang.Error: There is an incompatible JNA natice library installed on this system [...] To resolve this issue you may do one of the following: - remove or uninstall the offending library - set the system propery 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.

He added -Djna.nosys=true when running ALEX. This seemed to fix it, and it worked well afterwards.

We never had this kind of exception on any of our test machines. Because it is a JNA error, I assume it has something to do with Selenium and the web driver executable the student was using and the version of the JRE/JDK. Do you have any more information on that?

Here are some version numbers. He uses the chrome driver from the Alex tutorial.

• Windows 8.1 Enterprise
• Java x64 version 1.8.0_45
• Chrome 54.0.2840.71 m
• Chrome Driver 2.25 win32

We could not reproduce this error and it never occured on our testing machines ever since. So I close this issue.
