> Based on Bernard's code from:
> Capturing anonymous classes inside lambdas may fail to compile, because:
> -the captured variables are not detected correctly, because `LambdaToMethod...captureLocalClassDefs` needs to find the AST node for the given `ClassSymbol`, but it has not yet been added into the `localClassDefs`. The proposed solution is to re-order the tasks done for JCNewClass, and call the super implementation sooner. This will enter the `ClassSymbol` and corresponding AST node into `localClassDefs` before the capture variables detection.
> -inside the anonymous class definition, some references to the captured variables are replaced using a map that maps captured variables for lambdas (`lambdaTranslationMap`) - but inside the anonymous class, there the captured variables should be mapped using the anonymous class' map/proxies (to fields). The proposed solution is to clear `lambdaTranslationMap` before processing the anonymous class body.
