Symptoms

Not able to use a CAC smartcard as the java keystore to connect to a database via SSL using JDBC driver 12.2.0.1. When using the file based keystore or Oracle Wallet all works just fine; however, when using the CAC smatcard the error "java.io.FileNotFoundException: NONE (The system cannot find the file specified)" comes up.

 Documentation 3.5 Tokens as JSSE Keystore and Trust Stores shows that System.setProperty("javax.net.ssl.trustStore", "NONE"); and System.setProperty("javax.net.ssl.keyStore", "NONE"); are the proper way to do this; however the error seems to indicate it is looking for a file called "NONE".

Basically when using a regular Oracle wallet file (.sso file) as a keystore, the code works:

ERROR
-----------------------

java.io.FileNotFoundException: NONE (The system cannot find the file specified)



STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Set configuration of smart card as:
name = jdbctest
library = <DIR>\\opensc-pkcs11.dll
slot = -1
2. Specify keystore as 'NONE' and keyStoreType as 'Windows-My
