Description

Shutdown NB with several projects opened. Removed the cachedir (for 11.3beta2). Started NetBeans, did refactor rename of "isKeepingCursorInView" to "p_cv" (file is in log), got warning about java.util.ConcurrentModificationException. Hit continue (after all, it was only a warning) and nothing happened, including there was no message put into the log.

Easily reproduces from empty cachedir. The code is open source...

The stack trace has just over 1,000 entries.
