java openclient datetime-tz

It looks like there is still an issue with array fields in resultset (temp-table), date and datetime now works but not datetime-tz :(

Calling any procedure that returns a temp-table/dataset with one field being an datetime-tz array (extent) result in the following error. 

com.progress.open4gl.Open4GLException: Input result set error: com.progress.open4gl.Open4GLException: 0 (7176)

Seems to be a sequel of this, https://knowledgebase.progress.com/articles/Article/000052040... I can confirm any other data type works just fine (including RAW).

As a side note, is there any reason the entries in that list aren't native date objects for DATE/DATETIME fields? For all other data types the entries in the list are primitive Java data types (Integer, BigDecimal, bool, String, byte[])... for DATE/DATETIME those are GregorianCalendarHolder???

And, the ecore version there urge to be updated to a more recent one :)

Thanks,
