hi
right now, in the pr i created for this, my code goes like (inside
abstractregistry.java)
```
if(localCacheEnabled && !isAvailable){
try{
List<URL> cached=getCacheUrls(url);
if(CollectionUtils.isNotEmpty(cached)){
listener.notify(cached);
logger.info("Registry unavailable or not yet ready.
Loaded cached URLs for "+url.getServiceKey()+" : "+cached.size());
}
}catch(Throwable t){
logger.warn(INTERNAL_ERROR,"failed to load local
cache","","Failed to load chached registry data for "+url,t);
throw t;
}
}
```
but this fails tests because i think `isAvailable()` returns false not only
when the registry crashes, but also when:
-the registry hasn’t connected yet (say during startup)
-the client object is null (like in tests or mocks)
-the registry was shut down gracefully
