DnD operations to internal browser crash JVM
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=567422 which seems to be causing this for Simantics applications.
We can't automatically fix all old products built on Eclipse 4.14 but we want to create a replacement org.eclipse.swt.win32.win32.x86_64
fragment that contains the fix from 774e8731.
For tracking purposes 9534ebca picks the change to R4_14_maintenance branch.
