Avoid empty catch blocks:
powertools-idempotency/powertools-idempotency-dynamodb/src/test/java/software/amazon/lambda/powertools/idempotency/persistence/dynamodb/DynamoDBPersistenceStoreTest.java#L355
Empty Catch Block finds instances where an exception is caught, but nothing is done.
In most circumstances, this swallows an exception which should either be acted on
or reported.

Perhaps 'key' could be replaced by a local variable.:
powertools-idempotency/powertools-idempotency-dynamodb/src/test/java/software/amazon/lambda/powertools/idempotency/persistence/dynamodb/DynamoDBPersistenceStoreTest.java#L55
Reports fields which may be converted to a local variable. This is so because
in every method where the field is used, it is assigned before it is first read.
Hence, the value that the field had before the method call may not be observed,
so it might as well not be stored in the enclosing object.
Limitations:
* We can only check private fields for now.
* The rule is not aware of threading, so it may cause false positives in concurrent code.
Such FPs are best handled by suppression (see also the `ignoredAnnotations` property).

This utility class has a non-private constructor:
powertools-idempotency/powertools-idempotency-dynamodb/src/test/java/software/amazon/lambda/powertools/idempotency/persistence/dynamodb/DynamoDBConfig.java#L34
For classes that only have static methods, consider making them utility classes.
Note that this doesn't apply to abstract classes, since their subclasses may
well include non-static methods. Also, if you want this class to be a utility class,
remember to add a private constructor to prevent instantiation.
(Note, that this use was known before PMD 5.1.0 as UseSingleton).
