the class IndentationCheck method visitLambdaExpression.

@Override

        BlockTree block = (BlockTree) body;
        excludeIssueAtLine = block.openBraceToken().line();
        int previousLevel = expectedLevel;
        expectedLevel = block.closeBraceToken().column();
        scan(block);
        expectedLevel = previousLevel;
