Hi,

whatever I'm doing in Eclipse, I get an error.

At start up I get an error at Java tooling initializing. I get an error when I want to open a type. And it's always the same error.

For example, when opening a type I get:

An internal error occurred during: "Cache refresh".
2048

The error at the start up also prints the error code as 2048.

I'm using the most up to date version of Eclipse.

Do you know a way to fix this issue?

edit: Here the stack trace of the error at Java tooling initializing:
