In JDK 1.4 beta b55 JCK test api/java_security/cert/CertificateFactory/index.html#generate fails. It seems the fix of 4395895 (Cannot import certain X.509 certficates with the Sun JCA implementation) is causing this test to fail.

Below is minimized test that shows the difference between builds b49 and b55
