 * @test
 * @bug 8139436
 * @summary This test validates an iteration over the Windows-ROOT certificate store
 *          and retrieving all certificates.
 *          Bug 8139436 reports an issue when 3rd party JCE providers would throw exceptions
 *          upon creating Certificate objects.
 *          This would for instance happen when using IAIK 3.15 and Elliptic Curve certificates
 *          are contained in the Windows-ROOT certificate store.
 *          The test uses a simple dummy provider which just throws Exceptions in its CertificateFactory.
 *          To test an external provider, you can use property sun.security.mscapi.testprovider and
 *          set it to the provider class name which has to be constructible by a constructor without
 *          arguments. The provider jar has to be added to the classpath.
 *          E.g. run jtreg with -javaoption:-Dsun.security.mscapi.testprovider=iaik.security.provider.IAIK and
 *          -cpa:<path to iaik_jce.jar>
