The CertPathPKIXTrustEvaluator can then be configured with a CertPathPKIXValidationOptions which allows forcing revocation checking to true - in commit 84e1a379d3af1072a4e770aedb5b516fe6e22983.</p> <p style="margin: 10px 0 0 0">If revocation checking is forced to true and no static CRLs are defined, the system property com.sun.security.enableCRLDP or the security property oscp.enabled <b>must</b> be set to true, otherwise, revocation checking will deterministically fail. Even then, if these endpoints are do not exist in the certificate, revocation checking will fail. </p> <p style="margin: 10px 0 0 0">This 'advanced' deployment will need some strong documentation to avoid unexpected failures. It could be useful to 'validate' the injected trust evaluator e.g. if forced revocation checking is true, check either a static CRL is defined, CRLDP is enabled, or OCSP is enabled. This will at least prevent startup on obviously bad configuration. </p> </td>
