SpyTrain.java:48-51: we need to implement StLambdaQuiet...
The puzzle `1248-52399106` from #1248 has to be resolved: 

https://github.com/objectionary/eo/blob/4a80878e27a1e6d41b71b4d2ab4949b741a1c51f/eo-maven-plugin/src/main/java/org/eolang/maven/SpyTrain.java#L48-L51

The puzzle was created by rultor on 30-Sep-22. 

Estimate: 30 minutes,  role: DEV. 

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).
