> If we update the isolation level using SQL instead of JDBC and then join/resume a global
transaction, on ending the transaction, the isolation level of the local connection is not
restored. The problem seems to be in EmbedXAResource. So it happens with both embedded and
client driver. Client driver internally uses SQL to set the transaction isolation. So the
problem is more likely to be hit with the client. I will attach a repro and a draft patch
with more details.
