4.x: Unit test lambdaification 23 of 23

[akarnokd]

Will go over the unit tests in ASCII order of the classpath and classes.

ℹ️ Adds new grammar mistake checking.
ℹ️ Fixed typos and grammars via IntelliJ inspections

IntelliJ: Inspect -> RedundantCast, Inspect -> Anonymous type can be replaced by lambda
Search regexp: new\s+\w+(?:\s*<(?:[\s\w<>(\[\])?,.?]|\s*<[\s\w<>(\[\])?,.?]*>)*>)?\s*\([^)]*\)\s*\{

/* NFI */ = Not Functional Interface so break the regexp pattern

Resolves: #8080
