This came up when developing under windows.

I have have many native libraries. 2 for each platform [1 for 32 bit and 1 for 64 bit] that I am supporting.
I am shipping the those libraries within the jar. Only one of those libs will work so naturally I only want one file outside the jar. What I did was write the appropriate resource to a file with a generic name "library".
As you can see there is no extension. The file does not adhere to any of the platform specific naming rules. So I passed the absolute file path to

NativeLibrary.getInstance(String) 

but this will end up with

java.lang.UnsatisfiedLinkError: Unable to load library 'C:\mypath\library' : The specified module could not be found.
    at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:194)
    at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:283)
    at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:244)

even though the file is right there.

Changing the file's name to "library.dll" will have JNA load it correctly.

I initially was using a temporary file (File.createTempFile() and had the same issue because I left the extension as ".tmp".

So here is the request:
When an absolute path name is supplied please allow the file to be loaded no matter what the name is.

Thanks
