Objects passed by reference should be pinned

[tcleenewerck]

Hello Peter

I'm trying to use your library with Pharo 9 to connect to google firebase. When the Firebase class creates a connection in the method createJWTFromCertificate: . At the end of this method, the code jws compactSerialized is executed.

Deeper in the callstack JsonWebSignature>>signatureFor: signs the message send to create the connection.
A call is made to LcLibCrypto. However the object holding the message needs to be pinned. The method PointerUtils>primOopForObject: fails.

How can this be resolved?

Hi Thomas, sorry for the late reply. Actually,there seems to be another immediate problem, which may impact your issue here as well.

This library was developed in Pharo 8 (where I think it still works), but in Pharo 9, some things changed, and in the JSONWebToken library I am dependend on, that uses an OpenSSL-version which calls LibLcCrypto with an old mathodname #moduleName which has been change to something else in Pharo 9. I have opened an issue with JSONWebToken to see if the manager of that project can cahnge the baseline to load a different version of OpenSSL for Pharo 9. In the meantime, could you see if you could use Pharo 8?

OK, doing some more research resulted in me updating the baseline to Pharo 9 and using the correct branch of JSONWebToken (for openssl 1.1), and then I finally get the same error as you :)

It does seem like the objects to be pinned is ones created inside the JSONWebToken library and I am currently talking to the maintainer to see if he can solve the problem (or possible, if there is something I can do from my side).

Will update here as soon as I know more

Hi again Toma, Norbert Hart, the maintainer of JSonWebToken have been so kind to add the needed method inside the class I'm using in the library, so now it works again.

You might need to create a new P9 image to ensure that nothing gets cached in git (which it does sometimes)

Thank you Peter and thank you Norbert. I'll give it a try later this week.
