In all versions of Netbeans > 12.0, I regularly experience several different
problems when trying to refactor code. Anyone else running into these
issues?
1. When moving a class, NB will scramble the import statements of classes
that depend on the moved class.
2. When moving a class, NB will throw the following exception:
java.lang.NullPointerException: Cannot invoke
"java.util.Collection.contains(Object)" because "sourceFiles" is null

3. When renaming a class, NB will sometimes rename the file, but fail to
rename the actual class.
The refactoring problems are making development quite difficult.
