Some completions available in lightweight mode aren't available in standard mode

[RecursivePineapple]

This extension decided to start acting up for no reason. I thought that maybe one of the cache/data files got corrupted somehow, so I removed every vscode-related file I could find and reinstalled everything, but it was still acting up. It's been very finicky, but the most reliably-broken feature I've seen is that some completions aren't available when they should be - mainly expanding a method name into a method stub.

I tried several old extension versions that worked previously and they also refused to work properly. I typically use vscodium, but I've also tried with vscode proper and its open source release. I'm not sure what else I can try, every log I can find hasn't been very helpful.

Steps to reproduce:

1. Create a superclass with a method and implement it on a subclass
2. Either type out the name of the method, or use intellisense to find it
3. Control + space again to bring up intellisense
4. In lightweight mode, there will be one or more completions that expand to a stub version of the method. In standard mode, there aren't any completions available

Lightweight mode:

Standard mode:

Found another problem. For some reason, I can't control click builtin methods but if I hover over the method calls, I can see the javadocs. It also doesn't give me any intellisense completions.

These two errors are spammed in the extension host logs, but I'm not sure if they're relevant.

This one looks more useful (from the 'language support for java' logs).

This extension has broken almost completely. I can't control + click any built in types or methods, and there seems to be a memory leak in the lsp daemon. I don't have a second computer to run it on, but I'm guessing this is just a problem with arch because I can't find anything else to reset. Since the debugger extension also decided to stop working and both of these extensions are on life support, I'm going to switch to intellij for now.

If anyone knows of a decent extension that works the same, please let me know. Every other java extension I could find didn't work.
