This is a known bug that unfortunately has proven very hard to
reproduce. I personally have only seen it a couple of times in the
last year, and never when I had my debugger at the ready. :-(
Most of us run on Windows, except for those who recently
switched over to MacOS. If it occurs reliably for you on your
system, then perhaps we can try to duplicate that configuration
to at least give us a better shot at reproducing the problem.

How are you setting the classpath? You should be able to fix
the problem by putting the latest X10 runtime jar on the Libraries
portion of the "Java Build Path" from the Project Properties.
If that's not it, can you check whether there's anything relevant
in the Error Log view? ("Window" -> "Show View" -> "Other..."
-> "PDE Runtime" -> "Error Log")
