Is it possible that you are getting this exception during native DND? I
think that SWT may post DND errors using an asyncexec, which is what your
stack trace suggests.
If this is the case, SWT should report more information. You could look for
references to SWT.error within SWT's DropTarget class.

I found two ways to produce the exception:
1. When my diagram is drawn initially, a certain type of connection seems to
cause it. I removed all special drawing from that connection, it didn't make
a difference.
2. When I try to move a node in the diagram.
I don't think moving a node would be native DND, so the answer to your
question would be no.
