Oracle has recently certified the latest version of Oracle Forms and Reports, version 11.1.2.2.0, with Java 8 Update 5 (JRE only) as of this week as long as you are using Internet Explorer 9 or higher, Firefox 24+, or Chrome 34+ (not supported with Safari) according to the latest update to the Oracle Forms 11.1.2.2.0 certification matrix: http://www.oracle.com/technetwork/es/middleware/docs/oracle-forms-111220certmatrix-2087910.xls?ssSourceSiteId=otnen
For Oracle Forms applications, JRE 8 may work as it is now supported by Oracle with the latest version of Forms, but I would strongly recommend testing in a development environment first to make sure there aren’t any weird issues either on the Forms side or (more likely) on the Java side. Please note that Forms 11.1.2.2.0 is the only Forms version which is supported to use JRE 8; other versions such as 11.1.1.7.0 or 11.1.2.1.0 are not supported with JRE 8. However, Java Development Kit (JDK) 8 is still not supported with Forms. JDK mainly comes into play when installing and running Oracle WebLogic Server itself.
We did a short test and the Forms Side worked fine, but we had some trouble with our Java Bean integrated into our Applications.
