I think whether or not to pad needs to happen at the JCA level. That the
XAResource interface must be wrapped and when prepare or commit is called a new
Xid should be created based on whether padding should be done or not. We will
need the same for XAResource.recover as different XAResources
If my memory serves me right, we were concerned that other tx manager would not
like the padding zeros. Or there was a tx manager (Informix???) that did not
like the padding. It's been too long, sorry...
I wonder if JBoss Group now has resources to test this with different tx
managers.
