JavaCC java.lang.ClassCastException while parsing source files

[jmborer]

Apache NetBeans version

Apache NetBeans 29

What happened

I don't know how and when this happens, but sometimes I get a notification and when checkin the logs I see for example:

SEVERE [org.openide.util.Exceptions]

SEVERE [null]: Last record repeated again.

When this happens, the code parsing is broken ans consequently the completion and syntax colouring.
