Hi

I have the following problem:
I upgraded from 4.0.4 to 4.0.5 used the jems installer files, cause I got
some error messages with the ...aop.xml. This error is not coming anymore, but luckily a new one comes, which did not appear on 4.0.4
I use mysql 5.0.27 for persistence and i putted the mysql-ds in the deploy directory and the connector to lib.
here is the short version of the error:

INFO [WrapperDataSourceService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=DefaultDS' to JNDI name 'java:DefaultDS'
16:30:19,125 WARN [JBossManagedConnectionPool] Throwable while attempting to get a new connection: null
