I think I found the part of code that is causing the problem.
The file is
src/ch/fhnw/jbackpack/SelectRestoreDirectoryDialog.java
// check that user can change permissions of this directory
if (selectedDirectory.setWritable(false)) {
selectedDirectory.setWritable(true);
} else {
String errorMessage = BUNDLE.getString(
"Error_Restore_Directory_Unmodifiable");
errorMessage = MessageFormat.format(
errorMessage, selectedDirectory);
showError(errorMessage);
return;
}
It would be good enough to comment this part and recompile the program.
I have no experience in that.
May anybody help?
