Emmanuel Lecharny commented on DIRMINA-1034:
--------------------------------------------
What I don't get is how that could be an issue, considering that we are not
bundling the {{ConcurrentHashMap}} class (thus the internal
{{KeySetViewKeySetView}} class). This class will be pulled out of your
classpath, reardless of the version MINA has been built with.
Note that we will most certainly create a version built with Java 7, no matter
what. It's just a rethorical question.
Can you please describe precisely your running environment ?
Thanks !
