After installing the 2.1 GWT (google web toolkit) in Eclipse received the following error:
Exception in thread "main" java.lang.NoSuchMethodError: org.mortbay.thread.Timeout.(Ljava/lang/Object;)V

This indicates duplicate libraries.
To solve:
In eclipse, Press CTRL + SHIFT + T and search for: org.mortbay.io.nio.SelectorManager
Probably you will find more than one reference.
In my environment were found two:
-> com.google.appengine.eclipse.sdkbundle.1.3.8_1.3.8.v201010161055
-> com.google.gwt.eclipse.sdkbundle.2.1.0_2.1.0.v201010280102
In Java:
- 50% of problems are classpath,
- the other 50% of the problems resides in your own code
- and the remaining 50% is with the user ;o)
