Hello there,

since last version (2.5.3), I encounter this error while using multiple aws S3 clients:

[error] java.lang.IllegalArgumentException: No duplicate ExecutionAttribute names allowed but both ExecutionAttributes 17f26bfa and 2c7346a0 have the same name: SdkClientSpan. ExecutionAttributes should be referenced from a shared static constant to protect against erroneous or unexpected collisions.

Fortunately, this is an easy fix!
