----------------------------------------------------------------------
Agreed, we are using openfire 4.0.3, even latest openfire 4.1.3 is using this
Mina 2.0.7 version only.
How to update affected version in this bug
https://issues.apache.org/jira/browse/DIRMINA-988?
That bug has affected version as 2.0.8 only, could you add 2.0.7 as well?

> When one tries to shrink a buffer which minimal capacity is set to 0, and set
> the size to 0, it enter into an infinite loop.
> Bug https://issues.apache.org/jira/browse/DIRMINA-988 has created in 2.0.8 it
> was a similar bug, but the code is slightly different in 2.0.7. But the
> problem is same. We should acknowledge this issue is present in 2.0.7.
> This is due to this loop :
> {code:java}
> while (newCapacity >>> 1 >= minCapacity) {
> newCapacity >>>= 1;
> }
> {code}
