spring boot language server causing long waits for Java outline view when running in lightweight mode

[martinlippert]

Describe the bug
I am running the Java language support in Lightweight launch mode only. When I open a Java file and there is no Spring Boot tooling enabled, the outline view will show Java content pretty quickly.

However, when I have the Spring Boot tooling enabled, it takes a long time until the outline content from the Java tooling gets populated.

My assumption is:
VS Code asks all the language servers for the symbols on the file. The Spring Boot tooling waits for a timeout before it returns, and VS Code is waiting for the language servers to return something before it shows the combined results.

@BoykoAlex My assumption (but I haven't verified this) is that this is related to the changes to wait for projects to get resolved. Any thoughts here?

[martinlippert]

We definitely need to solve this before we can ship those changes...

[BoykoAlex]

Likely to be related to work we've done to wait for symbols to show... We'll have a look at it.
