Description

 I tried to set "https://docs.oracle.com/en/java/javase/12/docs/api/" in Java Platforms in Javadoc. (I do not know if it was this exact link)

I closed Java Platforms and then tried to open it again, but it did not open and the NullPointerException occurred.

Deleting my config folder under AppData\Roaming\NetBeans fixed this issue.

I was not able to reproduce this error. But the exception may help to find this Bug.
