We are working on a new big project for @graalvm — Project Crema: github.com/oracle/graal/i…. It will lift Native Image's default closed-world assumption by allowing dynamic loading and execution of classes at run time. Stay tuned for updates!

#Java Time Tip: Watch out for equals() vs isEqual() in date-time classes! ZonedDateTime, OffsetDateTime, and OffsetTime behave different: equals(): Compares all fields (including zone/offset) isEqual(): Compares instants (ignoring zone/offset) Same moment, different result
Same here! Great readability & powerful API
