On the Mac...
I've defined a Cache Connection to my local server. It worked for the last two days, but after an uninstall/reinstall of Atelier, it stopped working. The stack trace has these entries:
java.lang.RuntimeException: Can't read from secure storage node /com.intersys.eclipse.connmgr/ensrc
Caused by: org.eclipse.equinox.security.storage.StorageException: No password provided.
