Mina 2 problem - InvalidMarkException in java.nio.Buffer

[Yigal Rachman <yi...@uvic.ca>]

Hi, Folks:

I am biting the bullet and porting to Mina 2.0.0-M1.  Thus far, I seem 
to have resolved all the changes without much pain.  I love the look of 
the revised Mina - elegant and even simpler to use - wow!

I have, however, run into a problem which appears to come from the 
bowels of Mina.  Here is the exception I am seeing:

java.nio.InvalidMarkException
    at java.nio.Buffer.reset(Unknown Source)

    at java.lang.Thread.run(Unknown Source)

The message is clear enough: no mark has been set on the buffer, so a 
reset is not possible.  But it does look fishy.. perhaps a thread that 
is not properly synchronized?  Ideas, anyone?

Thank you all for your continuing help.
