Closing the client logs an exception

AmazonDynamoDBLockClient:955 logger.info("Heartbeat thread recieved interrupt, exiting run() (possibly exiting thread)", e);

Prints
[dynamodb-lock-client-1] INFO com.amazonaws.services.dynamodbv2.AmazonDynamoDBLockClient - Heartbeat thread recieved interrupt, exiting run() (possibly exiting thread)
java.lang.InterruptedException: sleep interrupted
at java.lang.Thread.sleep(Native Method)
at com.amazonaws.services.dynamodbv2.AmazonDynamoDBLockClient.run(AmazonDynamoDBLockClient.java:955)
at java.lang.Thread.run(Thread.java:748)

Which kind of looks like an error occurred.

In my opinion it should
a) Log as debug
b) Not log the stack trace

Start at AmazonDynamoDBLockClient.java around line 955 and inspect the heartbeat thread's interrupt logging path. Compare the current output with the requested behavior: the expected interrupt should not appear as an error or include a stack trace; verify the resulting log output.
