OK. Maybe we can look for some other smaller lib ;)

Jochen Theodorou commented on GROOVY-7977:
------------------------------------------

The negatives:
946k library size, which is quite big to jarjar, and we probably would have
requires java8, so cannot be used in 2.4 or 2.5

maybe if we take out only the parts we actually need, but then we would have to see what is left and since I know that this comes from guava, there might be still a big bunch of classes

>          I found the LRUCache that Groovy is using is not efficient enough because it is based on Collections.synchronizedMap, the LRUCache is used by some important classes(e.g. ProxyGenerator, Closure), so it can impact the performance somehow. 
>          I propose to replace the implementation with Caffeine(https://github.com/ben-manes/caffeine), which is a high performance caching library for Java 8 and licensed under APL2.
