Starting with Oracle Forms and Reports 11.1.2.2.0, the latest version of Oracle Forms available, support with Java Runtime 8 update 5 or higher has been added per the Oracle Forms 11.1.2.2.0 certification matrix (More information can be found in the Client tab in the certification matrix)http://www.oracle.com/technetwork/es/middleware/docs/oracle-forms-111220certmatrix-2087910.xls?ssSourceSiteId=otnen.
However, if your Forms application is using SSL (https), you may encounter the following error in your Java Console:
network: Connecting https://server.domain/forms/java/icons.jar with proxy=DIRECT
javax.net.ssl.SSLException: Received fatal alert: close_notify
network: Connecting http://server.domain:443/ with proxy=DIRECT
at sun.security.ssl.Alerts.getSSLException(Unknown Source)
at sun.security.ssl.Alerts.getSSLException(Unknown Source)
The Forms application will no longer work. According to the “Security Enhancements” page in the JRE 8 documentationhttp://docs.oracle.com/javase/8/docs/technotes/guides/security/enhancements-8.html, the TLS 1.1 and TLS 1.2 options were enabled in the Java Control Panel found on every client PC which connects to the Oracle Forms application. Previously in JRE 6 and 7, these options were either disabled or not present; however, it was enabled in JRE 8.
To fix the problem, in the client PC, follow the steps in our Knowledge Base:
