HotSpot crash log

We've been working on a major new version of our application for a while, and have an issue with the Mac build core dumping on exit.

This new version uses e4 and we've have this problem since Mars; not on Luna or Keppler, curiously, nor on our current e3-based version.

As it occurs on exit it's been hard to track down. Switching perspectives seems to be a guaranteed trigger - we have 3, 2 of which use the Nebula Grid.

We're now pretty sure org.eclipse.nebula.widgets.grid.Grid and its sizingGC field in particular is the cause of the issue and will submit a patch that resolves the issue for us.

I'm attaching the HotSpot crash log, and the Mac Crash Reporter log.

Moving to SWT for comments. 

org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.550.v20170928-1359

All, please see the proposed Gerrit patch for what solves a crash on Mac. Apparently holding on to a GC for many resize calculations makes the application crash on close-down.

You can imagine that we only want to incorporate this patch if it is absolutely needed.
