Java is configured to use SSLv2 encryption protocol.
To use the Symantec Protection Engine Console, java should be using TLS rather than SSLv2.
It is recommended to disable the setting 'Use SSL 2.0 compatible ClientHello format'
Java 8 - Scroll down to the section Advanced Security Settings
Uncheck the setting 'Use SSL 2.0 compatible ClientHello format'
