                 Key: FLINK-4130
                 URL: https://issues.apache.org/jira/browse/FLINK-4130

          Components: Table API & SQL
    Affects Versions: 1.1.0
            Reporter: Cody

In CallGenerator, when a call takes no operands, and null check is enabled, it will generate code like:

boolean isNull$17 = ;

which will fail to compile at runtime.
