The puzzle `152-6918ce7a` from #152 has to be resolved:

https://github.com/amihaiemil/docker-java-api/blob/ab0d78ec783de53306d63a66dd459598d58dc8c4/src/main/java/com/amihaiemil/docker/Images.java#L44-L47

If you have any technical questions, don't ask me, submit new tickets instead. The task will be \"done\" when the problem is fixed and the text of the puzzle is _removed_ from the source code. Here is more about [PDD](http://www.yegor256.com/2009/03/04/pdd.html) and [about me](http://www.yegor256.com/2017/04/05/pdd-in-action.html).

首先阅读 Images.java 的第 44-47 行以及 issue #152 中引用的谜题。确定其中还有哪些问题尚未解决，然后验证项目测试；当问题得到修复且谜题文本已从源代码中移除时，工作就完成了。
