I am using Findbugs and other plugins to analyze Java files.
An Issue has been generated for a specific Findbugs rule, even though the source code has not been modified.
In addition, there were cases where the status was set to close on its own, even though no operation was performed on the screen.
I would like to know if the same thing happens with Findbugs rules or other plugin rules.
I would also like to know the conditions under which such cases occur, if you know them.
The specific rules are as follows
Correctness - Value is null and guaranteed to be dereferenced on exception path
I am using the PMD and checstyle plugins, but I have not experienced the above events.
