JSDTProposalComputer es sólo un envoltorio paraNodeContentAssistant
(que implementaIContentAssistProcessor), que funciona perfectamente bien para TextEditor based Editor.

public class JSDTProposalComputer implements IJavaCompletionProposalComputer {

    IContentAssistProcessor assistant = new NodeContentAssistant();

    @Override
    public List<ICompletionProposal> computeCompletionProposals(ContentAssistInvocationContext context, IProgressMonitor monitor) {
        return Arrays.asList(assistant.computeCompletionProposals(context.getViewer(), context.getInvocationOffset()));
    }

    @Override
    public List<IContextInformation> computeContextInformation(ContentAssistInvocationContext context, IProgressMonitor monitor) {
        return Arrays.asList(assistant.computeContextInformation(context.getViewer(), context.getInvocationOffset()));
    }
