stankiewicz opened a new pull request, #37765:
URL: https://github.com/apache/beam/pull/37765

   This PR removes the `UnnecessaryLambda` check from the `disabledChecks` list 
in BeamModulePlugin.groovy and addresses all resulting compilation errors. The 
`UnnecessaryLambda` pattern flags lambdas that are saved in constants or 
returned from helper methods, recommending direct method implementations or 
method references instead. 
   I refactored these cases across the codebase, resulting in cleaner and more 
idiomatic Java code by utilizing method references where appropriate.
