Subject Re: NPE when refactoring with NB 11
Date Mon, 11 Mar 2019 18:02:05 GMT
Out of curiosity:  did you install nb-javac in your 11 installation?  Also,
you might check the amount of memory available to NB.

I have no idea if these may impact your issue but I think installing
nb-javac has had an impact (positive impact) on some of my code.refactoring
vs. not installing it.
There was a discussion on the dev list recently about the impact of NB
memory constraints.  It has been changed for 11 but I'm not sure which
build dropped it.  You might also try the latest daily build and see if it
helps the issues you are observing.
