All Implemented Interfaces:

JaxbContextCache
```
public class JaxbContextCacheImpl
extends java.lang.Object
implements JaxbContextCache
```
Simple cache based on ConcurrentHashMap without eviction. This implementation is aimed to avoid additional third party dependencies. For a more robust solution You can easily implement your own cache with Guava, Ecache, Caffeine or any other cache library. See some code references in the JaxbContextCache interface.
