Jan Lahoda commented on NETBEANS-4396:
--------------------------------------
A workaround is to disable Compile on Save (in Project Properties, select
Compile and uncheck the Compile on Save checkbox).
Pull request for a fix (automatically disable Compile on Save):
[https://github.com/apache/netbeans/pull/2163]
Compile on Save may be supported even without nb-javac in the future:
[https://github.com/apache/netbeans/pull/2128]
As Geertjan, I'd suggest to consider using Maven, nonetheless.

> As soon as I hit "Run" or "Debug". (I am right clicking the project in

> Update:
> I have the same issue on my other machine. It is only related to NOT having

> nb-javac is deactivated in order to be able to use switch expressions.
