Lorenz Bühmann commented on JENA-2225:
--------------------------------------
Not sure if opening a new issue would be better, but I guess we're not done
here. We didn't recognize this because apparently I didn't know TDB2 assumes
stats file in TDB2_LOCATION/DataXXX:
Now that the stats are being loaded, the change to long values leads to
additional parse errors during the reordering setup/application because there
are still integer values assumed:

> TDB/TDB2 dataset size stat serialized incorrectly for large datasets
> --------------------------------------------------------------------
>
> Key: JENA-2225
> URL: https://issues.apache.org/jira/browse/JENA-2225
> Project: Apache Jena
> Issue Type: Bug
> Components: TDB, TDB2
> Affects Versions: Jena 4.3.1
> Reporter: Lorenz Bühmann
> Assignee: Andy Seaborne
> Priority: Minor
> Fix For: Jena 4.4.0
>
>
> When computing the TDB/TDB2 stats via CLI the size will be serialized
> incorrectly for large datasets.
> For example for latest Wikidata Truthy we get
> {noformat}
> (count -1983667112)){noformat}
> This happens because for both the corresponding `Stats.java` class does
> enforce an Integer type Node though the value is a long type:
> {code:java}
> if ( count >= 0 )
> addPair(meta.getList(), StatsMatcher.COUNT,
> NodeFactoryExtra.intToNode((int)count)) ; {code}
