Bug 12593 code assist inserts fully qualified type names (ignoring preferences)
20020328 package p; import java.util.List; public abstract class Test { public void foo() { List l= new List(){<CODE ASSIST HERE>} } } choose the 'addAll' method (any of the two) you get the fully qualified name for Collections (although my java editor/code assist preference says it should insert an import statement)

declTypeBuf.append('.');
		}
		declTypeBuf.append(declaringTypeName);
		
		StringBuffer nameBuffer= new StringBuffer();
		nameBuffer.append(declaringTypeName);
		nameBuffer.append('(');
		if (parameterTypeNames.length > 0) {
			nameBuffer.append(getParameterSignature(parameterTypeNames, parameterNames));
		}
		nameBuffer.append(')');
		nameBuffer.append("  "); 
		nameBuffer.append(JavaTextMessages.getString("ResultCollector.anonymous_type")); 
	
		int length= end - start;
		
		return new AnonymousTypeCompletionProposal(fJavaProject, fCompilationUnit, start, length, new String(completionName), nameBuffer.toString(), declTypeBuf.toString(), relevance);
	}
	
	protected JavaCompletionProposal createTypeCompletion(int start, int end, String completion, ImageDescriptor descriptor, String typeName, String containerName, ProposalInfo proposalInfo, int relevance) {
