Starting audit...
[ERROR] /var/tmp/TestClass.java:16: 'lambda arguments' has incorrect indentation level 16, expected level should be 12. [Indentation]
Audit done.
Checkstyle ends with 1 errors.
The problem is that the IndentationCheck wants
this.<Function<List<?>, Boolean>>
test(
x -> z -> z.contains(x)); // Line 16
as it says:
incorrect indentation level 16, expected level should be 12
this is definitely a mistake. The indentation should be 16 as in other cases.
There should be no violation. The indentation on the line 16 should be 16, as in other cases.
