ADDITIONAL SYSTEM INFORMATION :
MacOS 10.15.1

Java 8 update 231

A DESCRIPTION OF THE PROBLEM :
We have had several customers report that on macOS Catalina, as soon as they open a save or open dialog, the app crashes.
I can't reproduce this locally.
The MacOS stack trace shows that it has crashed in libglass.dylib Java_com_sun_glass_ui_mac_MacCommonDialogs__1showFileSaveChooser

I have tried disabling System Integrity Protection on my Mac with macOS Catalina and can't reproduce this but we have had at least 4 customer reports of this.

We have fixed this locally by patching GlassApplication.m and ensure we never call GlassOpenPanel or GlassSavePanel, but use NSOpenPanel or NSSavePanel.

Here is the stack trace:
