In order to enhance security, the certificate revocation checking feature has been enabled by default starting in Java 7 Update 25. Before Java will attempt to launch a signed application, the associated certificate will be validated to ensure that it has not been revoked by the issuing authority. This feature has been implemented using both Certificate Revocation Lists (CRLs) and Online Certificate Status Protocol (OCSP) mechanisms.
Different options are available within the Java Control Panel to configure how the revocation checks are performed for the application you are trying to run.
