Description Tomas Hoger 2016-01-15 13:39:03 UTC 
It was discovered that the password-based encryption (PBE) implementation in the Libraries component of OpenJDK specified incorrect key length.  This could lead to generation of keys that were weaker than expected in certain cases.

  derived key may be different and not equivalent to keys previously derived
  from the same password.
