I tried to update my environment from SDK1.1RC8 to SDK1.1RC10. I started my application and got an exception when creating a new map: 
 
!ENTRY org.eclipse.osgi 4 0 2007-07-19 10:25:19.606 
!MESSAGE An error occurred while automatically activating bundle net.refractions.udig.catalog.arcsde (285).

I checked the plugins: 
plugins/net.refractions.udig.catalog.arcsde_1.0.1.jar doesn't contain any class file. The class ArcsdePlugin can only be found in  plugins/net.refractions.udig_platform.source_1.1.0 as source file. 
 
i wondered about the number 1.0.1 of the plugin and took the plugin out of 1.1RC8 which is 1.1.0
