Excessive lambda usage

Reports if a trivial lambda expression is used in cases in which there's an alternative method that behaves in the same way, but accepts a concrete value instead of a lambda.

This inspection helps simplify the code.

Example:

Optional.orElseGet(() -> null)

After the quick-fix is applied:

Optional.orElse(null)
