Start at com.alibaba.datax.common.util.Configuration.getList(Configuration.java:426) and com.alibaba.datax.plugin.rdbms.reader.util.OriginalConfPretreatmentUtil.dealJdbcAndTable(OriginalConfPretreatmentUtil.java:84), using the stack trace to follow PostgreSQL reader initialization. Obtain the failing job configuration and determine the expected value shape; done means the PostgreSQL reader initializes without this ClassCastException and the failure is covered by an appropriate regression test.
