Local fix

Problem summary

• The problem is caused when two security providers both provide
  one algorithm implementations and the higher priority one is
  selected by default, but the supportParameters() method of this
  Service object does not support the key type, only returns true
  for a quick, coarse check.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR11
  6.0.1 SR4
  .
  java.security.Signature has been updated to prevent the
  exception.
  

Temporary fix
