Hi, I can confirm this behavior for new JDK14 preview features records and instanceof expression. Running IDE with JDK14 default does not suffice. By the way. I only get the project (ant based) running if directly execute run target of build-impl.xml. "Official" way results in
java.lang.UnsupportedClassVersionError: javaapplication1/JavaApplication1 (class file version 57.65535) was compiled with preview features that are unsupported. This version of the Java Runtime only recognizes preview features for class file version 58.65535 Might be an ant integration issue with recompiling classes before executing the java process. (Remove compile on save helps!)
