Hi Paul,

Thanks, that’s great to hear! There was some concern expressed a while back 
that it might be impossible to move past Java 8 because of a change to the way 
classes are loaded. I’m definitely glad that turned out not to be the case!

Take care,
Mark

I know at least at one point there was an issue migrating past Java 8, due to 
the way WOnder patches/extends Apple’s frameworks. Has that been resolved or 
worked around? We would like to totally get rid of Java 8, and move to Java 11 
(or 17, or 21…).

Plenty of people have moved beyond Java 8. We've been using Java 21 since soon 
after it was released. About the only thing you'll need to do is add some JVM 
options in 
build.properties<https://urldefense.com/v3/__http:/build.properties__;!!MfzFaTml5A!kVqrmx58oqFRWdQNqzkgLBMqSjN9BNTffYpBV39CThLDnVveU0G69UQ1s-GThu7W_bSsufTI2G1LRfZyhX0cDO0ULtrRVWo$>,
 such as:

jvmOptions=--add-exports java.base/sun.security.action=ALL-UNNAMED 
--add-exports java.base/sun.util.calendar=ALL-UNNAMED

I'm struggling to think of much else that was required. It was certainly an 
easier transition than I thought it was going to be.
