Jim,
We are in the process of implementing X10 2.0 semantics in SVN HEAD.
There will be destabilizing changes.
For more details on the proto types, please see the recent discussion
on the x10-core list. In short, the message means that the instance
method in question is called from the constructor before the object is
fully initialized, and thus has restrictions on what it can access.
If you wish to stay with the X10 1.7 semantics, please build off the
x10-17 branch, or wait for the imminent 1.7.6 release.
