> In RpcProgramNfs3#commit() :
> {code}
>       Nfs3FileAttributes postOpAttr = null;
>       try {
>         postOpAttr = writeManager.getFileAttr(dfsClient, handle, iug);
>       } catch (IOException e1) {
>         LOG.info("Can't get postOpAttr for fileId: " + handle.getFileId());
>       }
>       WccData fileWcc = new WccData(Nfs3Utils.getWccAttr(preOpAttr), postOpAttr);
> {code}
> If there is exception, postOpAttr would be null.
> However, Nfs3Utils#getWccAttr() dereferences attr parameter directly.
