Hi,
We're using H2 (version 1.2.140) with connection string
"jdbc:h2:split:nioMapped:/
testDB;LOCK_MODE=3;CACHE_SIZE=262144;TRACE_LEVEL_FILE=0;DB_CLOSE_ON_EXIT=FALSE;MVCC=TRUE"
and we have a NullPointerException with this stack:
2010-08-06 10:34:25,895 WARN

This happened only twice since we're using 1.2.140, so I couldn't get
more info debugging (I'll try if I get this error again).
I've been reading the code and I suppose that there's a problem in
org.h2.store.fs.FileObjectSplit.getFileObject(), but I haven't found
anything obvious. Hope you can help.
Thanks!
