Improve start/stop of language servers

[angelozerr]

related to #838

The start/stop of language servers should be improved to avoid some freezing and some weird behavior like #752

In otherwise I would like to fix:

• Internal error with IDE stuck for seconds #720
• IllegalStateException: Synchronizer should apply to only a single document, which is the one it was instantiated for #752
• java.lang.NullPointerException: Cannot invoke "java.util.concurrent.CompletableFuture.thenRun(java.lang.Runnable)" because "this.initializeFuture" is null #748

I noticed that there are a lot of freeze and exceptions when I open a project, I close it, I reopen it and open another project, close them, etc quickly.

I had this problem on one of my projects where it also froze, I had to disable the plugin to make it work again. The project uses some advanced qute stuff which might not be yet handled by the plugin, but it should never freeze like this. This is really bad and should be taken seriously!

@ia3andy we're taking those freezes very seriously. Expect the quality and performance of the intellij-quarkus plugin to improve dramatically in the coming weeks.

Ah that is a very good news, I am eager to give this a try :)

Thanks for your patience!

Just one question, the freeze appears when:

• you are editing a qute template?
• you are closing editor?
• you are closing a project?
• you are closing IJ?

When I am opening a project containing qute templates, those qute templates are a bit exotic (fragment...)

I've managed to open it someway and I've got a lot of this:

in the projects it seems

've managed to open it someway and I've got a lot of this:

You are using Quarkus support from Jetbreains. This error desn't comes from intellij-quarkus.

So please tell me when freeze occurs.

I am using both at the same time, let me disable the intellij one

can you please take and share a thread dump whenever you see a freeze happening?

Performance and freeze problem should be fixed with #849

Please repoen if you find some again troubles
