Wei Tan reported this warning (taverna-hackers 2010-01-25) when creating a caGrid activity in 2.1.0:

It turns out that:

I found the issue, in
credential-manager-ui-1.0.jar\META-INF\services\net.sf.taverna.t2.security.credentialmanager.MasterPasswordProviderSPI
net.sf.taverna.t2.workbench.ui.credentialmanager.UIMasterPasswordProvider
should be
net.sf.taverna.t2.workbench.ui.credentialmanager.password.UIMasterPasswordProvider
That is, you moved the implementation to another package but forgot
to change it in the SPI declaration file

So the correct fix is to update the SPI file to use the correct class name.
