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.

> 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.
