Boolean literal serialization from GMF adding parens [message #902041]

I have an integrated Xtext/Xbase DSL and GMF graphical editor. I'm noticing a strange issue that I'm wondering if anyone has previously discovered or knows a work-around for.

My 'entities' support writing operations similar to methods. Some of these are specifically constraint related operations (eg. need to return boolean).

If I start with a statement like this in one of my operations:

var boolean flag = false;

When I have both editors up and make a change in DSL, GMF reloads the domain model. When I then make a change in GMF and save, GMF serializes my DSL (which seems odd since I'm just making a visual change that does not change the model, but I digress). Now my statement looks like this:

var boolean flag =( (false));

If I repeat this process more and more parens will build up around the initialization of this boolean variable.

Why are these extra parens being added and what can I do to prevent this?

Thanks in advance for any assistance!
