in Java 16 project
[ https://issues.apache.org/jira/browse/NETBEANS-5470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17304512#comment-17304512 ]

---------------------------------------------
NetBeans does not yet support JDK 16.
> Pattern matching marked as error in Java 16 project
> ---------------------------------------------------
>
> Key: NETBEANS-5470
> URL: https://issues.apache.org/jira/browse/NETBEANS-5470
> Project: NetBeans
> Issue Type: Bug
> Components: java - Hints
> Affects Versions: 12.3
> Reporter: Austin Stephens
> Priority: Major
>
> When one has a Java project using JDK 16 and has the source level set to 16, Netbeans still shows the use of pattern matching as an error even though it is no longer a preview feature. The code is question still compiles successfully.
>
> {code:java}
> public class Test{
> private boolean test(Object obj){
> if (obj instanceof String s){
> return s.isBlank();
> }
> return false;
> }
> }
> {code}
> 15 and 16 aren't listed in the source level drop-down for Netbeans Module projects, so you have to specify 15 or 16 directly in the properties file. That may be related, but I am not sure.
