Using iaik.pkcs.pkcs11 wrapper to communicate with cloudhsm on ubuntu.
When trying to retrieve all public keys of class RSAPublicKey I get this exception:
iaik.pkcs.pkcs11.wrapper.PKCS11Exception: CKR_ATTRIBUTE_TYPE_INVALID
at iaik.pkcs.pkcs11.wrapper.PKCS11Implementation.C_FindObjectsInit(Native Method)
at iaik.pkcs.pkcs11.Session.findObjectsInit(Session.java:642)
Using the logging pkcs11 wrapper I managed to find:

but cannot understand what's the problem. The mechanisms should all be allowed properly as well by cloudhsm.
From AWS support on this issue: cloudhsm does not accept any allowed mechanism attributes for the C_FindObjectsInit call.
