[Trustedjava-support] certifyKey() exception

[Maksim D. <dk...@bf...>]

Hi!

I have a problem with the certifyKey() method. The following code (where 
I try to use the predefined nonce for key certification), for example:

TcTssValidation validation = new TcTssValidation();
validation.setExternalData(nonceBlob);
//validation = keyToCertify.certifyKey (certificationKey, null);
keyToCertify.certifyKey(certificationKey, validation);

Simply throws exception:

java.lang.IllegalArgumentException: Argument 'validation' is not an 
instance of iaik.tc.tss.impl.java.tsp.TcRsaKey.
    at iaik.tc.utils.misc.CheckPrecondition.isInstanceOf(Unknown Source)
    at iaik.tc.utils.misc.CheckPrecondition.optionalInstanceOf(Unknown 
Source)
    at iaik.tc.tss.impl.java.tsp.TcRsaKey.certifyKey(Unknown Source)
    at TPMClient.certifyKey(TPMClient.java:170)
    at TPMClientTest.main(TPMClientTest.java:61)

However I find it weird, since the certifyKey() method declaration looks 
like:

TcTssValidation 
<http://trustedjava.sourceforge.net/jtss/javadoc_all/iaik/tc/tss/api/structs/tsp/TcTssValidation.html> 
*certifyKey*(TcIRsaKey 
<http://trustedjava.sourceforge.net/jtss/javadoc_all/iaik/tc/tss/api/tspi/TcIRsaKey.html> certifyingKey, 
TcTssValidation 
<http://trustedjava.sourceforge.net/jtss/javadoc_all/iaik/tc/tss/api/structs/tsp/TcTssValidation.html> validation) 
throws TcTssException 
<http://trustedjava.sourceforge.net/jtss/javadoc_all/iaik/tc/tss/api/exceptions/common/TcTssException.html>

Any info on that?

Maksim.

This is a bug - the wrong preconditions are being checked.
Thanks a lot for pointing this out! It will be fixed in the next release.=

(And, I will send you an hotfix per e-mail right away.)

One more thing: if possible, please post as complete code as possible -=20
if I am able to create a JUnit test out of it right away, debugging is=20
much easier.
