iOS Question Can I upgrade JRE on mac without breaking builder


Licensed User
I'm not a mac expert so didn't want to do something I couldn't reverse. I have b4ibuildserver working perfectly on local mac. I have a b4xpages project that works under b4j and b4i. The b4j project works fine on Windows, for fun I wanted to see if it ran on MacOS. When I try to run b4j project on mac I get this error:

Exception in thread "JavaFX Application Thread" Exception in thread "main" java.lang.UnsupportedClassVersionError: b4j/example/main has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Seems to indicate a newer version of JRE is required. When I go to it recommends "Version 8 Update 381" to install this on mac and not break b4ibuildserver?
