Hi all,
I am currently using Jena 2.10.0 plus associated components and I am
sometimes running into an exception. Unfortunately, I don't have a
reproducible test yet as it seems (as usual) not to happen consistently.
But looking at the code, I am not sure what I am seeing. The problem is in
the journal, where the JournalEntryType seems to be 0 (valid values seem
to be 1 - 6). Anyone has any idea how this could happen? Perhaps I am
doing something wrong here. I noticed in my code I am executing a commit
during a read-only transaction. I will remove this, but I thought this was
legal. Anything I am missing?
thanks
Simon
