I am trying to sign with CMSSignedDataGenerator and IBMPKCS11 (I access an
IBM Thales HSM through a Websphere server) and I have this error: 

org.bouncycastle.operator.RuntimeOperatorException: exception obtaining
signature: java.lang.NullPointerException

        ... 4 more 
                
I have added BouncyCastle Provider libraries to lib/ext and java.security
but I still have the error. 

On the other hand, I can perfectly sign with SunPKCS11.	

Thanks in advance for your help.
