Inefficient code in LambdaToMethod

This code in visitIdent is horribly inefficient since every call to getSymbolMap creates a fresh new instance of a translationMap. There should be a single method which returns a pair of LambdaSymbolKind and the translated symbol



            if (lambdaContext.getSymbolMap(PARAM).containsKey(tree.sym)) {
                Symbol translatedSym = lambdaContext.getSymbolMap(PARAM).get(tree.sym);
                result = make.Ident(translatedSym).setType(tree.type);
                translatedSym.setTypeAttributes(tree.sym.getRawTypeAttributes());
            } else if (lambdaContext.getSymbolMap(LOCAL_VAR).containsKey(tree.sym)) {
                Symbol translatedSym = lambdaContext.getSymbolMap(LOCAL_VAR).get(tree.sym);
                result = make.Ident(translatedSym).setType(tree.type);
                translatedSym.setTypeAttributes(tree.sym.getRawTypeAttributes());
            } else if (lambdaContext.getSymbolMap(TYPE_VAR).containsKey(tree.sym)) {
                Symbol translatedSym = lambdaContext.getSymbolMap(TYPE_VAR).get(tree.sym);
                result = make.Ident(translatedSym).setType(translatedSym.type);
                translatedSym.setTypeAttributes(tree.sym.getRawTypeAttributes());
            } else if (lambdaContext.getSymbolMap(CAPTURED_VAR).containsKey(tree.sym)) {
                Symbol translatedSym = lambdaContext.getSymbolMap(CAPTURED_VAR).get(tree.sym);
                result = make.Ident(translatedSym).setType(tree.type);
            } else {
                //access to untranslated symbols (i.e. compile-time constants,
                //members defined inside the lambda body, etc.) )
                super.visitIdent(tree);
            }
