For NetBeans running on JDK 11, I could find out about at least one problem:
In org.netbeans.api.java.source.TreeUtilities, there's a reference to
Kind.RECORD (line 112), which exists only as of JDK 16. So, when running
on JDK 11 this leads to an error.

Kind regards,

Peter

The first message ("Markup im Dokument nach dem Root-Element muss

root element must be well-formatted."

Kind regards,

Hello,

in the mean time, I've tried creating a Java hint following the
tutorials using different versions of NB (12.4, 12.6) on different OS
(Linux, Windows) without success, so I give up.

However, when trying to use Ant, I'm not able to build the module
project, either:

warning: No processor claimed any of these annotations:

org.netbeans.spi.java.hints.Hint,org.netbeans.spi.java.hints.TriggerPattern

/home/peter/NetBeansProjects/Geertjan/HintDemoWithAnt/src/org/nb/hintdemo/JOptionPaneHint.java:31:
error: cannot access TreePath
         return ErrorDescriptionFactory.forName(ctx, ctx.getPath(),
Bundle.ERR_JOptionPaneHint());
   class file for com.sun.source.util.TreePath not found
1 error
1 warning

Can anybody help me?

Kind regards,
Peter
