Detailed description:

While compiling I receive such error:

Is it error in library or I am doing something in wrong way? 

Could you please explain to me the most probable causes of such error and how 
to avoid them? I could not  find any information about subject.

Are you using runAsync()  in your app?   I think this message is trying to tell 
you that is not supported.   There is a compiler flag -XdisableRunAsync that 
might allow the gadget to compile.

Thank you for your answer.

>> Are you using runAsync()  in your app?  
Maybe somewhere in others code. I am not sure.

>>  There is a compiler flag -XdisableRunAsync that might allow the gadget to 
compile.

Could you please explain two moments:
1. What exactly this flag mean? If I use it can I use  runAsync()  in this case?

2. I have to compile several modules in one project, how can I use this flag to 
affect only to one particular module (gadget), and not to the others?

I just looked at the latest GWT source code and the XSLinker that the Gadget 
linker inherits now appears to support runAsync(), so you might try compiling 
with a more recent version of GWT. 

Here's the detail of the change which was made 2 years ago:

Yes, it seems really works with GWT 2.1.0 but not with 2.0.4
