When a SunPKCS11 provider instance if constructed, it loads the PKCS#11 library and calls C_Initialize(). We expect it to return CKR_OK and fail when we get CKR_ALREADY_INITIALIZED.

This is an issue with PKCS#11 libraries that may have already been initialized by other code within the Java process. For example, if used within the JES WS/IS, the NSS softtoken may have been initialized already.
