Regex support with 'CompareOperation.CONTAINS' on expected datasets

In my test case I’m declaring

  @Test
  @ExpectedDataSet(
      value = "dataset/expecteddata.yml",
      compareOperation = CompareOperation.CONTAINS)
  void myTest() {
    ...
  }

When running the test I got the following exception:

...
13:28:01.295 [main] DEBUG org.dbunit.dataset.FilteredTableMetaData - getFilteredColumns(tableName=myschema.mytable, columns=[(pse_id, BIGINT, noNulls)], columnFilter=org.dbunit.dataset.filter.DefaultColumnFilter[_includeMatcher=org.dbunit.dataset.filter.PatternMatcher[_acceptedNames=[STATUS, MANDATE, OPERATION, OBJECT_TYPE, PAYLOAD, OBJECT_BK], _acceptedPatterns=[]], _excludeMatcher=org.dbunit.dataset.filter.PatternMatcher[_acceptedNames=[], _acceptedPatterns=[]]]) - start

After a bit debugging, I found that I must add the primary key column to the expected data set. Because I can’t know the actual Id’s in advance, I added a regex pattern:

myschema.mytable:
- pse_id: regex:\d+
  some_field: ...

while ‘pse_id’ is my primary column of type BIGINT.

But now I get a TypeCastException - almost at the same location: DataSetExecutorImpl.java:931

Did anyone else encounter the same issue? Is there a solution or a known workaround - except using CompareOperation.EQUAL (which bloats the data set in my case)?

Thanks in advance!
