Hi Jasper,
I have no idea what this can be caused by. IIRC I never saw a similar
warning.
Triggered by your question I looked into the manifest of
org.eclipse.net4j.db.mysql and I realized that the package imports don't
have version numbers.
In HEAD I changed now to the following:
Import-Package: com.mysql.jdbc;version="[5.1.0,6.0.0)",
com.mysql.jdbc.jdbc2.optional;version="[5.1.0,6.0.0)"
But I don't know if that will fix your problem. Sorry!
If it persists I'd suggest to ask the Equinox gurus about the warning.
Cheers

Eike,
I've found a way of reproducing this. I open the CDOServer.launch
configuration in the "Run Configurations" dialog. I deselect all
plugins, then add
org.eclipse.cdo.server
org.eclipse.cdo.server.db
org.eclipse.net4j.db.derby
org.eclipse.net4j.db.mysql
org.eclipse.net4j.db.hsqldb
org.eclipse.net4j.db.postgresql
followed by "Add required plugins". This gives me a config including 29
plugins, which, on startup, gives the error I reported below.
So I compared my hand-built config and the one in your CVS. I found one
plugin present in my hand-built config that's not present in yours:
com.springsource.javax.transaction (1.1.0)
It gets added when I hit 'Add required plugins', apparently because
com.springsource.com.mysql.jdbc imports its packages. One can wonder
indeed if it's wise for the dialog to add plugins that aren't explicitly
required when the user clicks 'Add required'...
Anyway, just putting this info up here in case anyone else ever dares
use the 'Add required plugins' button when constructing a run config for
CDO.
Regards,
Jasper.

Hi jasper,
Thanks for the update.
Btw. you can control whether to include optional dependencies or not
before you hit "Add Required Plug-ins". There's a checkbox at the bottom
of the page.
Cheers
