Alex Herbert commented on MATH-1633:
------------------------------------
Replacing SpotBugs 3.1.8 with 4.3.0 allows the spotbugs plugin to run in JDK
17. The build then fails on bugs found by SpotBugs. These are not detected
using JDK 8 with SpotBugs 3.1.8.
SpotBugs is skipped in the {{commons-math4-legacy}} module so this relates to
updated code. I had to fix the legacy code to use the updated API from Commons
Statistics.
The errors are related to exposing a reference to a private field through
getter methods. I inspected a few and this seems intentional.
I added this to the spotbugs exclude filter:
{noformat}
<!-- Disable checks for exposure of internal references.
TODO: Revise this to use more targeted exclusions. -->
<Match>
<Or>
<BugPattern name="EI_EXPOSE_REP"/>
<BugPattern name="EI_EXPOSE_REP2"/>
</Or>
</Match>
{noformat}
The code then almost builds on JDK 17. It fails for the legacy module as
AccurateMath does not implement all java.util.Math methods.
I have pushed the update to master.
