Hi Li,
The missing piece is that you are supposed to call setValueCount() on the
mutator when you are done writing to it.
that would be 2.5 in your original email.

You can use the approach in the test suite:

If the Java folks have some other recommendations, I'll let them chime in.

To answer myself: the above doesn't work because mutator doesn't update
writerIndex (only ArrowBuf.writeXXX does).
Still wondering if there is a good way of setting validity map in Java?
