hamada commented on SOLR-11892:
-------------------------------
specifically the code of interest where an IOException is thrown :
@Override
public void deleteFile(String name) throws IOException {
ensureOpen();
RAMFile file = fileMap.remove(name);
if (file != null) {
file.directory = null;
sizeInBytes.addAndGet(-file.sizeInBytes);
} else {
// FIXME there are no file operations here this method removes fileName entry
from a map, it isn't per se removing deleting a file!
throw new FileNotFoundException(name);
}
}
> Avoid unnecessary exceptions in FSDirectory and RAMDirectory

> In privateDeleteFile, just use deleteIfExists.
> in RamDirectory we can declare a static exception and create it once.
