Apache MINA vs JGroup

[Matthieu Labour]

Hi,
I am new to both JGroup & Apache MINA
Maybe my question is silly. How do Apache Mina and Jgroup compare to each
other? I guess Apache Mina doesn't support multicast yet and JGroup does but
if Mina eventually supports multicast what would be the use cases where Mina
is more suitable than JGroup?
Thank you
