Description Aurelien Pupier CLA 2013-02-05 03:17:45 EST 
Build Identifier: 3.0.0

FilePath l.1163
Please also add the file path.
"Native function mod failed on file: "+f.getAbsolutePath()
I have thousands times this error in log but I don't know on which files it is happening.

Reproducible: Always
Comment 1 Winston Prakash CLA 2013-02-05 11:40:46 EST 
BTW in which platform this is happening? Hudson native use native access (by accessing the native library like LibC) to do some native stuff like chmod, link etc (needs jna-native-support plugin). If it fails to load the library or the JNA native access plugin is not found, it simply prints out the message and switch to non native method. It is only information, not error. 

Looks like the info is displayed too many times. I'll fix it to not to display again and again.
