The following results in NullPointerException

new Win32FindData().clone();

Exception in thread "main" java.lang.NullPointerException
    at com.jniwrapper.Structure.computeLength(SourceFile:231)
    at com.jniwrapper.Structure.init(SourceFile:168)
    at com.jniwrapper.Structure.init(SourceFile:176)
    at com.jniwrapper.win32.io.Win32FindData.init(Win32FindData.java:65)
    at com.jniwrapper.win32.io.Win32FindData.<init>(Win32FindData.java:60)
    at com.jniwrapper.win32.io.Win32FindData.clone(Win32FindData.java:166)
    at com.ci.pl.app.os.core.win32.util.Win32DirectoryStream.main(Win32DirectoryStream.java:523)

I do this for many other structure classes and it works. I noticed this issue when I tried to perform:

new ComplexArray( new Win32FindData(), 2);

Thanks,

Rob Arciere

Hello Rob,

Thank you for reaching out!

This appears to be a bug of the WinPack structure definition.
The modified WinPack wrapper with the fix is attached to this reply. The complete WinPack source code can be found in the "WinPack/src" subfolder of the JNIWrapper distribution archive.

Please let me know in case of further questions.

By the way, could you please let me know which company you represent?

Sincerely,

Nataliya Rybynok
