It could some kind of access issue, but my expectation would be that it would just bomb out completely if it tried to open or write to something that you don't have permissions for. But I can't say for sure.
I think you're onto something with the FileSystemPreferences, those are the default Preferences used by Java on Linux, and NetLogo does read and write to them for a few things. It's possible to set a different Preferences handler by Java switch, so I'll see if I can make up a dummy one you can try out. If it doesn't hang, at least we'll know the culprit even if we don't know why. -Jeremy On Thursday, March 18, 2021 at 2:54:59 PM UTC-5 Charles wrote: > I've run this under both JDK 11 and 1.8 (Java HotSpot(TM) 64-Bit Server VM > (25.281-b09 mixed mode)), with the same results (attached).
