Well it was still happening, but I traced to a piece of code in just one file. It was compiling but something about NetBeans did not like it at all and was throwing this error. I used 12.5 on JDK17 and 11 and then 12.6-RC2 on JDK17 all throwing the same error. I can only imagine there was something corrupt in the file. I removed that excerpt and suddenly no problem. I rewrote the logic block in the same file and low and behold no issue. I moved the offending block to a new file and the NPE pops up again. I would love to share it, but it’s closed source so we’ll chalk this up to something inept that I did!!
Thanks Neil!
