--------------------------------------
Hi Tim,
we have something here. It uses CachingService [1], which implementation uses
EhCache [2, 3].
It requires a good review as it isn't fully tested (and it's a core change).

> DSpace org.dspace.core.Context caching problem

> Key: DS-1205
> URL: https://jira.duraspace.org/browse/DS-1205
> Project: DSpace
> Issue Type: Bug
> Components: DSpace API
> Affects Versions: 1.8.2
> Reporter: DSpace @ Lyncode
> Priority: Blocker
> Labels: Core
> Fix For: 3.0
>
>
> bin/dspace script is crashing with OutOfMemory problems related with the
> org.dspace.core.Context HashMap.
> Proof: https://github.com/lyncode/DSpace/issues/5
> I think this is a critical problem, mainly because it does not make sense
> (for me) to have crashing applications because of caching mechanism memory
> overusage. As good practices for implementing caches, this cache mechanism
> could be aware of it's memory usage threshold, if reached, it could start
> discarding old and unused objects in it.
