My company IT department is starting to asked about when our vendors are planning to discontinue JAVA JRE browser plugin support. Per the Oracle link below our IT department will be retiring the Java browser plug-in in September 2018. Java 8 will be end of life in September and our IT team will remove it from our desktop/laptops and will not deploy Java 9. We're currently using Java 7 with 9.4.2.1, but we're upgrading soon to 10.2.2 which will use Java 8. My team will need to come up with an internal solution outside of corporate IT to support Java 8 so we can launch OneClick after September. If my company is moving away from JRE I'm sure others are to which means CA needs to start looking at other plugins to support OneClick in the future.
