Unable to handle/refresh DynamicConfiguration in case of AWS s3's token expired

[cdash415]

When accessing S3 using session token it valids for 3600mins(1hr), so till 1hr Archaius polling is all good. But after 1 hr while Abstract polling schedular tries to poll from s3, getting token expired exception from amazon & I have no way to update the DynamicConfiguration with updated S3 client as the schedular keeps trying connect to s3 bucket with already given s3 client . Need a way to allow refreshing the s3Client and pass this to DynamicConfiguration.

Below bean is responsible to initiate the archaius polling from s3. Tried keeping it inside try-catch to see if exception raised for first time(after 1 hr of token generation) it will retry the DynamicConfiguration with updated client. But exception is not reaching to this catch.

public DynamicConfiguration dynamicS3Configurer1() {
	DynamicConfiguration dynamicConfiguration = null;
	String s3PropPath = s3Config.getResourceFolder() + fileName;
	try {
		dynamicConfiguration = new DynamicConfiguration(new S3ConfigurationSource(s3Config.getS3Client(), s3Config.getBucketName(), s3PropPath),
new FixedDelayPollingScheduler());
	} catch (Exception e) {
		e.printStackTrace();
		if (e instanceof AmazonS3Exception) {
			//retrying here
		}
	}
	return dynamicConfiguration;
}

Exception stack:
