iOS Question Can I upgrade JRE on mac without breaking builder

[scGuy]

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 java.com it recommends "Version 8 Update 381" ...safe to install this on mac and not break b4ibuildserver?

You have to use packager to make the application run on mac.

Any version of Java (8+) will work with B4i builder. In order to run B4J apps on Mac follow this: https://www.b4x.com/android/forum/threads/macsigner-building-notarized-mac-packages.130890/#content
