New Java Language Features with Eclipse
summary
Six-month Java releases add concrete features (instanceof patterns, switch expression yields a value, records, sealed types) and Eclipse updates the Eclipse Compiler for Java and JDT to support them. Records generate constructors/accessors/hashCode at compile time and records require VM changes; implementing records and sealed types surfaces about 25 compile errors during testing. Eclipse adds a record-creation wizard that needs the --enable-preview project flag, a quick-fix to convert mistyped return to yield, and clearer NPE messages that name the null field.
