JCK tests verify that AuthProvider implementation throw LoginException if the login operation fails.
sun.security.pkcs11.SunPKCS11.login throws NPE if null value passed to the method. This behaviour contradicts with the spec.

These tests failed only when running in Java plugin, the failure reproduced constantly.
First of all, run tests in Java plugin is a standard feature of JavaTest. JavaTest UG desribes all neccesary steps!
In addition, the failing tests can be run via JCK QA scripts:

1. ssh moonblade.russia.sun.com
2. mkdir -p /tmp/ProviderTests/tmp
3. mkdir -p /tmp/ProviderTests/workdir
4. mkdir -p /net/archer.russia.sun.com/export4/jck/tmp/ProviderTests/resultsdir
5. export TEMP=/tmp/ProviderTests/tmp
6. cd /net/archer.russia.sun.com/export4/jck/sqe-bin/QATools/bin
7. ./qa_latest -tc p002 -tcsuff _ProviderTests -testtype promoted -mailto <e-mail_address> -iu api/java_security/AuthProvider/ProviderTests.html -display moonblade.russia.sun.com:0.0 -workdir /tmp/ProviderTests/workdir -resultsdir /net/archer.russia.sun.com/export4/jck/tmp/ProviderTests/resultsdir
