Hello, there are multiple features that works on jdk 1.8 but not on jdk 1.7. Since we also support jdk 1.7 on 6.3 they should be working. List of features:

• camel-jbpm
• camel-optaplanner
• camel-pgevent (since R13)
• camel-salesforce
• camel-xstream (already reported here )
• drools-dependencies
• kie-remote-dependencies
