Review Comment:
in fact we're using `SerializableMap` mainly due to Kryo ser/de so I'm
surprised that this ended up being an issue.
I've also added
```
@Test
public void testKryoSerialization() throws IOException {
AwsClientProperties props =
new AwsClientProperties(
ImmutableMap.of(AwsClientProperties.CLIENT_REGION, "us-east-1",
"k1", "v1"));
AwsClientProperties deserialized =
TestHelpers.KryoHelpers.roundTripSerialize(props);
assertThat(deserialized.clientRegion()).isEqualTo(props.clientRegion());
}
```
to `AwsClientPropertiesTest` but that passes with Kryo ser/de.
If you e.g. run this test but change `allProperties` to be an
`ImmutableMap`, then you would see that `allProperties` is actually the
underlying issue for Kryo ser/de and the stack trace would look something like:
```
java.lang.UnsupportedOperationException

The reason we use `SerializableMap` for Kryo is because Kryo can't deal with
Immutable collections and in most other places we pass around an
`ImmutableMap`. So in order to make `AwsClientProperties` work with Kryo, we
keep the properties in a `SerializableMap`.
In your case the issue seems to be due to
`java.lang.IndexOutOfBoundsException: Index 113 out of bounds for length 28`.
