All tests in ITDMLTest.java relies on the same INSERT_DML statement. Each test executes the INSERT_DML & DELETE_DML statements, except abortOnceShouldSucceedAfterRetry test. All tests executed after abortOnceShouldSucceedAfterRetry will fail with "Row already exists" error.

Short term fix:

• add the DELETE_DML into the test too

Correct / Long term fix:

• refactor the test cases to not rely on the same set of INSERT/DELETE_dml statements. These tests should be independent (dont try to create a database/create a new table for each test, that will make them slow). Let each test run its own unique INSERT DML that does not interfere with another tests execution.
