Issue with history and casecomment batches

[nihi-lb-dk]

The execute method in the class brf_BatchableRetryJob will throw an exception when the batch operates on history sobjects i.e. accounthistory, claimhistory. CaseComment has the same issue

A sobject instance cannot be created for those types with the following call: //errorId points to either claimhistory, casecomment etc sObjectType.newSObject(errorId);

I'm "solving" this with a switch case. However I'm not satisfied with this solution since I'll need to rewrite the brf_BatchableRetryJob.execute method each time a new batch is introduced that operates on the history objects/casecommments etc...

public void execute(Database.BatchableContext ctx, List<brf_BatchableError> scope) {
    // One batch scope here represents an entire previously failed batch scope
    brf_BatchableError error = scope[0];

    // Construct an SObject scope to pass to the execute method
    // TODO: Support non-SObject scopes
    List<Id> scopeErrorIds = error.JobScope.split(',');
    SObjectType sObjectType = scopeErrorIds[0].getSobjectType();
    List<SObject> retryScope = new List<SObject>();
    for (Id errorId : scopeErrorIds) {
        SObject sObj = null;
        switch on error.ApexClassName {
            when 'BatchAccountHistory', 'BatchAccountHistory_2' {
                sObj = Schema.getGlobalDescribe().get('AccountHistory').newSObject();
                sObj.Id = errorId;
            }
            when 'ClaimHistory' {
                sObj = Schema.getGlobalDescribe().get('ClaimHistory').newSObject();
                sObj.Id = errorId;
            }
            when else {
                sObj = sObjectType.newSObject(errorId);
            }
        }

        if (sObj != null) {
            retryScope.add(sObj);
        }
    }

    // Invoke the execute method on the original batch apex job class
    Type apexJobClassType = Type.forName(error.ApexClassName);
    Database.Batchable<SObject> batchJob = (Database.Batchable<SObject>) apexJobClassType.newInstance();
    batchJob.execute(ctx, retryScope);
}

An better solution for this issue would probably to extend the brf_BatchableErrorHandler interface with a method that returns the sobject type i.e. 'ClaimHistory' or 'Account' etc.. => then utilize that in the execute method
