Hi
I have this stack with Jena 3.6.0 , alas non reproductible .
The calling non-Jena code does this (in Scala ) :
val results = solutions.iterator.toIterable.map {

I saw that *BufferC**hannelFile.java* has changed since 3.6.0, this is now
an interface.
I don't not understand -- BufferChannelFile is not an interface.
There are two such classes - TDB1 and DBOE/TDB2.
The TDB1 used here has not changed in a couple of years.
A corrupted nodetable might cause this. It's not a mode of failure I
recall having been reported but it is possibly consistent with that.
Or a concurrency failure.
