So it's nearly useless if you want to cache random data, which is very likely to be requested again without being Hard-linked the rest of the time. The b...
Is there softreference-based LinkedHashMap in Java? If no, has anyone got a snippet of code that I can probably reuse? I promise to reference it correctly. Thanks. ...
