LRUSoftCache - Should use SoftReference to support OOME
-------------------------------------------------------
Key: CAMEL-3922
URL: https://issues.apache.org/jira/browse/CAMEL-3922
Project: Camel
Issue Type: Improvement
Components: camel-core
Reporter: Claus Ibsen
Assignee: Claus Ibsen
Fix For: 2.8.0
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.
