Lionel,
Do you only get this error on JNDI datasources? Have you tried the
default viewer to see if you get the same issue?

Were you able to try the viewer in the runtime download?

I tried this with the viewer and tomcat/mysql connection pooling and did
a reload and did not see the issue. I assume you setup connection
pooling like:

Can you open a bug for this? I can not reproduce the issue. I have
