Hi Steve, in the line
597 Map<Integer,List<Name>> versionsMap = stream() I miss space after the comma. In the line 626 return finalNames.stream().map(nm -> getJarEntry(nm)); You can use a method reference instead of lambda: 626 return finalNames.stream().map(this::getJarEntry); And if you add a method #getName() to the Name class, then you can use method references in the lines 604 and 614 too. +1 to Tagir's suggestions. Best regards, Andrej Golovnin
