------------------------------------
Summary: syscs_import_data_lobs_from_extfile can not read data
past 2GB
Key: DERBY-6836
URL: https://issues.apache.org/jira/browse/DERBY-6836
Project: Derby
Issue Type: Bug
Components: Store
Reporter: martin stanik
syscs_util.syscs_import_data_lobs_from_extfile() imports data from .csv file.
For binary data, in csv is expected a reference, where should be data read from.
The reference is in form:
<filename>.<offset>.<length>
The offset and length are implemented as int.
Hence, it is not possible to read binary data which are stored after 2GB.
The stack trace is like:
