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

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:

Tái hiện kịch bản superclass/subclass trong VS Code, so sánh kết quả completion ở chế độ nhẹ và chế độ tiêu chuẩn. Bắt đầu bằng việc xem xét các vị trí trong stack trace của JDT LS, bao gồm BundleUtils.startBundle và FoldingRangeHandler, cùng với hành vi completion được báo cáo; hoàn thành khi chế độ tiêu chuẩn cung cấp các completion method-stub giống như chế độ nhẹ mà không có các lỗi được ghi log.
