Hi,
I've encountered a BufferOverflowException using MVStore when stuffing a
load of xml files into a store. It only seems to occur with a specific
number of writes of various sizes. I've distilled the test case down about
as far as I can.
Can you please check if it breaks for you.
I've using the a build of the latest SVN trunk.
The exception is:
java.nio.BufferOverflowException

Test case below.
Thanks,
