Hi Folks!

I am having an issue using NativeLibrary directly. I was initially using jna from groovy where the problem first showed up but I have since created the simplest possible case in plain java to demonstrate the problem.

import com.sun.jna.NativeLibrary;

public class TestJna { public static void main(String[] args) { NativeLibrary lib = NativeLibrary.getInstance("User32"); lib.dispose(); } }

Environment: jna 3.0.9, Java 1.5.0_12, Windows XP

Executing the provided class results in the following exceptions to the console upon exit.

java -cp .\jna.jar;. com.sun.jna.Native$DeleteNativeLibrary c:\Temp\jna63722.tmp error=193 at java.lang.ProcessImpl.create(Native Method) at java.lang.ProcessImpl.<init>(ProcessImpl.java:81) at java.lang.ProcessImpl.start(ProcessImpl.java:30) at java.lang.ProcessBuilder.start(ProcessBuilder.java:451) at java.lang.Runtime.exec(Runtime.java:591) at java.lang.Runtime.exec(Runtime.java:464) at com.sun.jna.Native$DeleteNativeLibrary.run(Native.java:761)

Process finished with exit code 0

I understand what the code in Native is doing and found that the error 193 means: ERROR_BAD_EXE_FORMAT %1 is not a valid Win32 application.

Anyway... Is this a known thing or should a new issue be created?

Thanks
