It seems then it will not be working if someone tries to connect to sftp server at windows environment. But it seems very strange that no one complained about it. Are you aware if there is any workaround like any other library updates (jsch) for 2.4.1 or something else that it might work?

Hi All,
Just checked that the patch has been removed form SftpFileObject
protected PosixPermissions getPermissions(final boolean checkIds) throws
Exception {
statSelf();
boolean isInGroup = false;
if (checkIds) {
for (final int groupId : getAbstractFileSystem().getGroupsIds()) {
if (groupId == attrs.getGId()) {
isInGroup = true;
break;
}
}
}
final boolean isOwner = checkIds ? attrs.getUId() ==
getAbstractFileSystem().getUId() : false;
return new PosixPermissions(attrs.getPermissions(), isOwner, isInGroup);
}
