On our RHEL 8.6 Linux x86_64 test machine, a couple of sun/security/pkcs11 tests fail.
Below are a number of examples. It looks like the native libs of the system do not support any more RSA keys with 512 bit length.
Should the tests be adjusted so that some keys are not tested any more in case the system is too new?

Examples of errors :

sun/security/pkcs11/KeyStore/Basic.java
