Start with Configuration.java:getList and OriginalConfPretreatmentUtil.java:dealJdbcAndTable, then reproduce the SQL Server reader job using the configuration and stack trace shown. Trace how the connection jdbcUrl value is read; done means the job no longer fails with ClassCastException for the reported configuration and the expected connection format is verified.
