Thanks a lot for the code review, I've submitted a test case for the corresponding code fix, please help me review again. @chernser

[chernser]

this is not a good practice - if someone change an original method then test will not be verifying a production code.
Please just make compileSql package private. This is ok because tests sometimes need to do so.

[chernser]

please remove this class.
