-----------------------------------

             Summary: Legacy X.509 certificate handling code should be upgraded
                 Key: NIFI-1753
                 URL: https://issues.apache.org/jira/browse/NIFI-1753
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 0.6.1
            Reporter: Andy LoPresto
            Assignee: Andy LoPresto


There are multiple instances throughout the codebase [1][2] where legacy `javax.security.cert.X509Certificate` class is used rather than the current (Java SE 6) `java.security.cert.X509Certificate`. The `javax.*` classes are provided for legacy compatibility with JSSE [3][4]. This can manifest as an exception:

`java.lang.ClassCastException: [Ljava.security.cert.X509Certificate; cannot be cast to [Ljavax.security.cert.X509Certificate`

The `CertificateFactory` class allows conversion to the new format.
