    In the new server wizard, when configuring a tc server, it is sometimes possible to press the Finish button before the SpringSource tc server has been configured. To reproduce: 0. Start Eclipse cleanly (i.e. with "clear" in the runtime configuration). 1. Go to the Servers view. 2. Right click and select New->Server. 3. Select Spring Source->SpringSource tc Server v2.1 from the tree of possible servers. 4. Select Next. 5. Fill in an installation directory. 6. Press the Finish button. The following errors appear on the console: !ENTRY org.eclipse.jface 4 0 2012-01-12 17:18:32.754 !MESSAGE Unhandled event loop exception during blocked modal context. !STACK 0
