Stephen Allen commented on JENA-279:
------------------------------------
Thinking about it a little more, I guess the purpose of the cache is to save
memory by sharing references to Nodes, not to prevent object creation. But I
think that really ought to be the responsibility of whatever container is
storing a large number of nodes. I would think that there are a lot of cases
where Nodes are ephemeral, and storing the in a cache seems like a waste.
Especially nodes created during ARQ's query processing.
> Make node cache configurable and use soft references

> It would be nice to offer the possibility to configure the NodeCache capacity
> and to use soft references in order to collect references when no more memory
> is available. The Node cache should not be the cause of an OutOfMemory error.
