Dev build, Mustang. Start IDE. With no projects open, press Ctrl-N. Exception
thrown. Should rather do nothing, or beep, or something.

It seems to me that this was introduced in revision 1.19 of
revision 1.19
date: 2005/05/17 00:15:43;  author: jglick;  state: Exp;  lines: +7 -2
Threading fix, avoids stack trace.

The problem is IMO following:
1. The user presses Ctrl-N, on an instance of NewFile action
"createContextAwareAction" method is called with appropriate Lookup (in the AWT
Thread probably).
2. New "NewFile" action is created (newly created actions have isEnabled() == true).
3. In the NewFile's constructor, "refresh" is called. The refresh replans to AWT
Thread to perform setEnabled and setDisplayName. (originaly, the setEnabled was
called synchronously in the refresh method).
4. isEnabled() is called on the newly created action (returns true as the
setEnabled(false) has not been runned yet), and as the result is true,
actionPerformed is called (resulting in the exception).

Please note that the action should be enabled only if
"OpenProjectList.getDefault().getOpenProjects().length > 0" and in such a case
calling OpenProjectList.getDefault().getOpenProjects()[0] seems OK.

Yup, needed to change enablement synch if already in EQ.
