Pressing CTRL-R cause Error

After updating to the lastest version

eclipse.buildId=4.25.0.I20220831-1800

I get the following error:

```
An internal error occurred during: "Cache refresh".
Cannot invoke "org.eclipse.jdt.internal.compiler.util.JrtFileSystem.walkModuleImage(org.eclipse.jdt.internal.compiler.util.JRTUtil$JrtFileVisitor, int)" because the return value of "org.eclipse.jdt.internal.compiler.util.JRTUtil.getJrtSystem(java.io.File, String)" is null
```

Working is next to impossible!

[eclipse-config.zip](https://github.com/eclipse-jdt/eclipse.jdt.core/files/9567225/eclipse-config.zip)

Start by reproducing the error after updating to Eclipse build 4.25.0.I20220831-1800 and pressing CTRL-R, then inspect the attached eclipse-config.zip and the JRTUtil.getJrtSystem and walkModuleImage calls named in the error. Done means the cache refresh completes without the reported internal error.
