Classes often won't show up when typing, but complete just fine in an import statement.

Had already used import org.springframework.security.test.context.support.WithMockUser; without issue.
Tried adding @WithSecurityContext to same class.

As I was typing, only 4 With* classes showed up (there are 6), and not the one I needed.

I go up to the imports, duplicate the WithMockUser line, delete "MockUser", hit Ctrl+Space, and all 6 With* classes show up! Why does it work here, but not at the class annotation?

I expect these would always show up.

I expect that after typing the full proper class name, that Ctrl+. would find the class and offer to import it.

If I type "@with", hit Ctrl+Space to bring up completion (still just shows the 4), continue with "Se", the suggestions are logical, but once I hit "c" I would expect the suggestions to go away, as there are no more logical ones. However, it stays up - no matter how much I hit Ctrl+Space to update it. (It appears like me activating it with my earlier Ctrl+Space has now prevented it from closing, even when the data is completed outdated, until you click away or hit Esc.)

Having a single minor issue preventing virtually all completion from working is already annoying enough, can't we have at least 1 thing that's nice?

Environment

• Operating System: Windows 10 + WSL 2 Ubuntu
• JDK version: WSL 2 Ubuntu openjdk-21
• Visual Studio Code version: 1.90.2
• Java extension version: 1.31.0
• Spring Initializer project init'd a few days ago - current.

Annotations have a @Target type to indicate the context in which the annotation is applicable. So if you don't see a particular annotation, it's usually because it cannot be applied in that context. Looking at the sources of these classes from a Spring Initializer project ..

@Target({ ElementType.METHOD, ElementType.TYPE })
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Documented
@WithSecurityContext(factory = WithMockUserSecurityContextFactory.class)
public @interface WithMockUser {

So @WithMockUser can only be applied to a type declaration, or method declaration.

@Target({ ElementType.ANNOTATION_TYPE })
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Documented
public @interface WithSecurityContext {

so @WithSecurityContext can only be applied to an annotation declaration, like in the example above. Maybe https://docs.spring.io/spring-security/site/docs/4.2.x/reference/html/test-method.html#test-method-withsecuritycontext explains it better ?

@jdneo , do you remember why this behaviour occurs ? Specifically initiating completion by typing a character correctly removes all items when a character typed doesn't match anything, vs. initiating competion with "ctrl + space" incorrectly preserving all items when a character typed doesn't match anything :

Is there a known upstream issue for this ?

Is there a known upstream issue for this ?

I'm not aware if there is an issue for this upstream. But I tried it in TS, which is exactly the same behavior.

completion.mp4

At least this does not seem to be an issue with the JLS implementation.

I can confirm the behaviour is exactly the same with just typescript, which indicates this is probably something worth checking upstream.
