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:

Reproduce el escenario de superclase/subclase en VS Code, comparando los resultados de finalización en los modos ligero y estándar. Empieza revisando las ubicaciones del stack trace de JDT LS, incluidas BundleUtils.startBundle y FoldingRangeHandler, junto con el comportamiento de finalización informado; se considera terminado cuando el modo estándar ofrece las mismas finalizaciones de métodos auxiliares que el modo ligero sin los fallos registrados.
