We have a daily analysis running on the master branch (similar to the one running after a PR merged, the whole repo scan).
But, there were new bugs (with the same bug type) suddenly popped up for our old code yesterday. The bug is This method's return value is marked "@NotNull" but null is returned, which is belong to the "@NonNull" values should not be set to null rule (java:S2637).
The log seems normal, same with the previous scans.
Any idea why the bugs suddenly appeared?
