1. create policy , it is normal : I can find it in memory and mysql

2. I try to remove them using
   enforcer.removeFilteredNamedPolicy(pType,0,e);
   enforcer.removeGroupingPolicy(id, parentId);
   remove p and g policy, but I found the data in memory is removed, but the data in mysql is still there

3. version info:

The reason is that the retry mechanism used by addPolicy() in jdbc-adapter-2.2.1 turned off the autocommit of the connection and forgot to reopen it, resulting in no automatic commit in removePolicy.

It's has been fixed in jcasbin/jdbc-adapter#50. Try jdbc-adapter lastest version.
