Start with PrioritySorterConfiguration.java at updatePriorities line 179 and configure line 99, then inspect the attached FullStacktrace.log and configuration XML files. Reproduce updating Global Settings with the reported Jenkins 2.249.3 and Priority Sorter Plugin 3.6.0 configuration, and confirm the update no longer throws a NullPointerException.
