Description Esa Ryhänen

Build Identifier: M20110210-1200

Content assist will not show any proposal when the prefix ends with a period ('.').

Reproducible: Always

Steps to Reproduce:
1. Create following Xtend2 class:

package test
class X {
   def func() {
       var aa = new java.util.|  // pipe (|) is where CA is activated.
   }
}

2. Activate content assist as indicated above.

The parser performs some strange error recovery for the given scenario.
One could introduce something like this:

QualifiedNameWithDot:
	QualifiedName '.'?
;

and use that one here

XConstructorCall returns XExpression:
	{XConstructorCall}
	'new' constructor=[types::JvmConstructor|QualifiedNameWithDot] 
	..
;

and in the XAnnotation rule. However, additional validation would be necessary to catch errors like

new java.util.ArrayList.(5)

and the fix cannot be easily applied to 

def java.util.|<EOF>

or def String foobar(java.util.|<EOF>

I'll investigate further in the error recovery issue
