Root cause is that the test materializes and installs a policy by [obtaining
the current
policy](https://github.com/openjdk/jdk/blob/4be2173478bd1e84946bd903b350ce466bddb36b/test/jdk/sun/security/pkcs11/KeyAgreement/IllegalPackageAccess.java#L46).
At the time it [tries to remove a
provider](https://github.com/openjdk/jdk/blob/4be2173478bd1e84946bd903b350ce466bddb36b/test/jdk/sun/security/pkcs11/KeyAgreement/IllegalPackageAccess.java#L80),
the materialized policy is used for an access check, due to some intricacies
of the [java.security.Policy
implementation](https://github.com/openjdk/jdk/blob/4be2173478bd1e84946bd903b350ce466bddb36b/src/java.base/share/classes/java/security/Policy.java#L293).
This policy does not allow the removal of a provider.
On platforms where the test runs through
[PKCS11Test::fetchNssLib](https://github.com/openjdk/jdk/blob/4be2173478bd1e84946bd903b350ce466bddb36b/test/jdk/sun/security/pkcs11/PKCS11Test.java#L859),
the default policy is reset which makes the test work. But if we don't pass
there, the test fails.
The fix is to unconditionally call Policy.setPolicy(null); in
IllegalPackageAccess before installing MyPolicy.
