It looks like the javax.security.cert.X509Certificate constructor (line 133) is trying to read the "cert.provider.x509v1" security property without wrapping the "java.security.Security.getProperty" call in a doPrivileged block (see stack trace below). As a result of this, non-JSSE code on the stack also requires the corresponding java.security.SecurityPermission ("getProperty.cert.provider.x509v1"), which is undesirable.

access: access denied (java.security.SecurityPermission getProperty.cert.provider.x509v1 )
