This error is related to certificate inaccessibility. Whenever Java attempts to connect to another application over SSL (e.g.: HTTPS, IMAPS, LDAPS), it will only be able to connect to that application if it can trust it. The way trust is handled in the Java world is that you have a keystore (typically $JAVA_HOME/lib/security/cacerts), also known as the truststore. This contains a list of all known Certificate Authority (CA) certificates, and Java will only trust certificates that are signed by one of those CAs or public certificates that exist within that keystore.
