FULL PRODUCT VERSION :

ADDITIONAL OS VERSION INFORMATION :
Mac OS Sierra 10.12

A DESCRIPTION OF THE PROBLEM :
I am developing an application using derby and all was ok. Suddenly some of my customers start complaining that the application was very slow after upgrade to sierra.

I was confused since I had no problem myself with sierra. And have been looking for a solution for some days without success. I use NetBeans 8.1.

Today this morning I worked on my program with some issues and then went for a walk and when I came back I suddenly had the same problem without changing anything?!

And when I run the profiler trying to track down the problem, the program was ok?!

I am confused. When I run the profiler it+s ok but when I run it or debug it it is terribly slow.

My application involves Derby and only occur on Mac OS SIERRA.
