Browser's accepting certificates that Java does not

[Sean Mullan]

Also, in case you did not know, the JDK "PKIX" CertPathBuilder 
implementation (which is also the default used by the JSSE TrustManager) 
supports retrieving certificates via the AIA extension, but it is 
disabled by default. To enable it, set the 
"com.sun.security.enableAIAcaIssuers" system property to the value "true".
