  The TLSv1 and TLSv1.1 protocols are considered weak.  If
  WebSphere is configures with the protocols a warning is issued
  recommending the user configure to use TLSv1.2 or higher.

• Issuing warning if customers are configure with TLSv1,
  TLSv1.1, or SSL_TLS.  Also issuing a warning when configured
  with SSL_TLSv2 as it can allow for TLSv1 and TLSv1.1.
