Hi everyone,
after my leave, I spent some time adopting the latest TDB-TX build (August
31) and I noticed I kept seeing the same problems as before. After some
messing around, I noticed that the patch Paolo attached to Jena-91 was not
actually applied to the sources in this latest TDB 0.9.0 snapshot (
tx-tdb-0.9.0-20110831.124751-10). When I updated the tx-TDB component from
SVN and looked NodeTableTrans, it seemed that the patch was not applied
there either, so perhaps it was not actually delivered ? Paolo, can you
please verify this?
Anyhow, I manually applied the patch on this build, but I keep running
into the same problems. The first exception that shows is :

This seems to be the same as what I saw before. It is possible I am still
messing something up by manually applying the patch, I'll definitely keep
looking at that. If I can get a new TDB 0.9.0 build with the patch
applied, I will definitely check again
