org.cache2k:cache2k-all (maven):  A light weight and high performance Java caching library. Android and Java 6 compatible. To avoid classloader problems the combined jar file cache2k-all is no longer supported. Please remove the cache2k-all dependency from your projects. For transition this depends on cache2k-api and cache2k-core.
