Description Michael Rennie CLA 2015-02-10 11:51:26 EST 
Consider the following snippet:

@Namespace foo url('my.url');

if you hover over the '@Namespace' token you get an exception in the console:

Error computing hover tooltip
tooltip.js:376 TypeError: Cannot read property 'type' of undefined
    at Object.internalRegistry.handleServiceError (http://mrennie-target.orion.eclipse.org:9000/orion/pluginregistry.js:1071:29)
    at Object._messageHandler [as handler] (http://mrennie-target.orion.eclipse.org:9000/orion/pluginregistry.js:392:55)
    at http://mrennie-target.orion.eclipse.org:9000/orion/pluginregistry.js:1117:33
    at Array.some (native)
    at _messageHandler (http://mrennie-target.orion.eclipse.org:9000/orion/pluginregistry.js:1106:23)

The problem is the short-circuit case when the token range is within the very first token.
