adt signing issue

Using macOS and signing with eToken. Was working before I upgraded to os x 10.14 as this broke the PKSC11 signing.

Installed an updated driver for SafeNet and the keytool is working again.

However when I try to sign using adt I get the following:

adt -sign -storetype PKCS11 -providerName SunPKCS11-eToken -storepass XXXXX -tsa http://sha256timestamp.ws.symantec.com/sha256/timestamp -target air APP.airi APP.air

unexpected failure: Unable to create signature.

java.io.IOException: Unable to create signature.

Using keytool I get:

keytool -list -keystore NONE -storetype PKCS11 -providerclass sun.security.pkcs11.SunPKCS11 -providerArg eToken.cfg

Enter keystore password: 

Keystore type: PKCS11

Keystore provider: SunPKCS11-eToken

Your keystore contains 1 entry

xxxxxxxxxx, PrivateKeyEntry,

Certificate fingerprint (SHA-256): xxxxxxxx

Any ideas on how to proceed?
