I tried to update some old xml layer config to the Annotation config in my plugin(https://github.com/hantsy/click4nb).

for example, 

@NbBundle.Messages({"CLICK_RESOVLVER_NAME=Click Config File"})
@MIMEResolver.Registration(
   displayName = "#CLICK_RESOVLVER_NAME",
resource = "ClickResolver.xml")
public class ClickMimeResolverRegistration {
}

But it did not support mutil @MIMEResolver.Registration in one class, I have two Resolvers in this project.

I have to create another one in the project.

@NbBundle.Messages({
    "CLICKMENU_RESOVLVER_NAME=Click Menu Config"})
@MIMEResolver.Registration(
   displayName = "#CLICKMENU_RESOVLVER_NAME",
resource = "MenuResolver.xml")
public class MemuMimeResolverRegistration {
}


why not supports like this:
@NbBundle.Messages({
    "CLICKMENU_RESOVLVER_NAME=Click Menu Config"})
@MIMEResolver.Registrations({
     @MIMEResolver.Registration(
         displayName = "#CLICKMENU_RESOVLVER_NAME",
         resource = "MenuResolver.xml"),
     @MIMEResolver.Registration(
         displayName = "#CLICK_RESOVLVER_NAME",
         resource = "ClickResolver.xml")
)
public class MimeResolverRegistration {
}

The original layer.xml supports mutil resovlers in the "MIMEResovler" nodes, why one class only support one @MIMEResolver.Registration.


BTW: personally, I am disappeared when I use the newest Annotation to config plugin, obviously this  MimeResolverRegistration is no use at all(I have to create a empty class to register????), and the annotation @MIMEResolver.Registration is only use for translate info into xml at compiling time.

This did not improve any programming experience.

I hope Netbeans can provide rumtime annotations to improve the programming model, such JSR330, it is supported in Eclipse e4.x, the NetBeans team rejected my  issues directly about this.
