Reproduce the Windows Preferences > PMD > Rule Configuration import flow after deleting all rules. Start with RuleSetSelectionDialog.selectedRuleset and updateRuleTable, then trace the RuleSetFactory exception for the EmptyCatchBlock exclusion. Done means selecting a rule-set file no longer raises the event-loop error and the imported rules appear in the table.
