If something is missing in an Apache project, it's because you yourself
personally haven't added it.
Here's where your missing feature is implemented for Java in NetBeans:

I am really looking forward to the Netbeans 10 release, right now I am using v3.
But I wonder when the time is to fix the "minor" bugs which make the coding
more fun. E.g. this: https://issues.apache.org/jira/browse/NETBEANS-360 😊
