Error building Babylon in Fedora 41

[Juan Fumero]

Ok, nevermind.
   Installing an older JDK 24 version works. For example this one:

```
sdk install java 24.0.2.r22-mandrel
```

Subject: Fw: Error building Babylon in Fedora 41

Hi all,
   I recently updated my system from Fedora 39 to 41, and I get the following error during the building of the code -reflection project.


```bash
Compiling up to 2 files for COMPILE_DEPEND

My configuration summary seems to be correct:

Any idea about how to fix this?
