I get an "SWTError: No more handles" when trying to display >=2^12
elements in a GMF-generated diagram. I thought this problem could never
occur because of using Draw2D figures for visualization of diagram
elements (so instead i would expect a "out of memory" exception..).
Stack trace:

.....
The strange thing about this exception that statically created cursors
(which are created only once) are assigned.. its not the case that for
each model element a new SWT cursor is created, which could explain the
problem somehow.
Thanks in advance for any comments
PS I used GMF 1.0.x
