Sorry for the problem.
We just fixed a problem on our NetBeans Integration. That, some jars are missing in our NetBeans plugin.
In our testing, if starting NetBeans with Java 11 JDK specified, the missing jar will make FileNotFound exception and make NetBeans failed to start.
FYI, in my testing, Java 8 can start NetBeans; Java 11 cannot; and since Java 9 and 10 are end-of-supported, I cannot test them.
Please update the software to latest patch build (20181130am or later) to get the problem fixed. Details about update to latest patch can be found at
Sorry, my testing is done in Windows, the problem occurs when starting NetBeans.
But for Mac user, seems no problem on starting NetBeans, but the problem occurs when starting VP.
(I don’t have testing environment on Mac, sorry)
I think the problem is also coming from missing jars in our NetBeans plugin, so, the above fixing should be able to solve on MacOS.
