Why does my SSL certificate not work with the Tomcat Native Library?

Issue

• SSL was working with existing certificate before the Tomcat Native library was installed.  However, now I have installed the Tomcat Native library and I am not able to get the APR connector to use my existing PKCS12 keystore.  I get the following exception:

ERROR [Http11AprProtocol] Error initializing endpoint java.lang.Exception: No Certificate file specified or invalid file format
                at org.apache.tomcat.jni.SSLContext.setCertificate(Native Method)

ERROR [org.apache.coyote.http11] (MSC service thread 1-4) [] [] [] JBWEB003043: Error initializing endpoint: java.lang.Exception: No Certificate file specified or invalid file format

• Not able to use Native connectors, due to above SSL exception
