Thanks for investigating this. Please move the discussion over to dev@ as it seems a problem with NetBeans Platform itself and more NetBeans developers will be on dev@ than users@.
It's unclear to me why the application crashes. Clearly we would have learned about it so far, NetBeans does have some users on macOS and I've been using NetBeans on Mac exclusively for ages. So... there must be something about how your code behaves too. Could you report the issue on JIRA (on https://issues.apache.org/jira/projects/NETBEANS/issues ) and also make a small module/class reproducing the bug and attach it to the issue? PS: Not sure what you mean about recompiling the package. If the fix will get added it will be part of the next Apache release. If you need commercial help, it is available from a few people https://netbeans.apache.org/help/commercial-support.html , including me. --emi ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On 1 May 2018 2:24 PM, frederic <frede...@ancestris.org> wrote: > Dear all, > > I have found a bug in Netbeans on MacOS which makes the applications crash on > MacOS.
