Claus Ibsen commented on CAMEL-3922:
------------------------------------
Attached a SoftQueue patch, which is for a Queue that uses SoftReferences as
well. We can use that for the ServicePool cache.
> LRUSoftCache - Should use SoftReference to support OOME

> We should creata a LRUSoftCache that uses SoftReferences for cached values.
> This supports the JVM when it runs low on memory and want to re-claim unused
> objects from the cache.
> We can use this for a certain number of caches where this is feasible such as
> - endpoint cache
> - producer cache
> - consumer cache
> Currently end users can only set a fixed max size on those cache.
