Problem summary

• When using KeyTool to generate a certificate and have it signed
  with
   an existing CA, KeyTool creates the Authority Key
  Identifier
   extension based on the CA's public key.
   Section "4.2.1.1. Authority Key Identifier" of
  RFC5280 states the
   following: "Where a key identifier has been
  previously established,
   the CA SHOULD use the previously established
  identifier."
   So if the CA certificate was not generated by
  KeyTool, its Subject
   Key Identifier might have been generated slightly
  differently, i.e.,
   not just the public key but with some other pieces
  of data. The end
   result is that when the new certificate is used in
  TLS
   communication, the client may throw a validation
  error(although the
   CA is indeed in the trust store)
  

Problem conclusion

• KeyTool was modified to copy the signing certificate Subject Key
   Identifier extension value to the signed certificate
  Authority Key
   Identifier extension value.
