A DESCRIPTION OF THE REQUEST :
Java 6 for Windows 64 bit was lacking in support for sun.security.pkcs11.SunPKCS11 feature and actually missing the required JAR and DLL file. Almost all other Java 6 and 7 platforms include the required JAR and native library (i.e. .so or .dll). The same was the case for SunMSCAPI but this has been included in Java 7 release for Windows 64 bit but support for SunPKCS11 is still not provided in Java 7

JUSTIFICATION :
There MUST be consistent support for the feature in Java for all platforms

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The application code using class sun.security.pkcs11.SunPKCS11 should be run on Java 7 for Windows 64 bit as it does for all other supported platforms
ACTUAL -
The application successfully running on Windows XP 32 bit fails on Windows 7 64 bit with following Exception:

java.lang.NoClassDefFoundError: sun/security/pkcs11/SunPKCS11
