Fix a UT failure unrelated to this PR

This unit test failure is not caused by this PR. The same failure occurred in April 2025 and was partially addressed in PR-1049:

#1049.

https://github.com/aws-observability/aws-otel-java-instrumentation/blob/release/v2.11.x/exporters/aws-distro-opentelemetry-xray-udp-span-exporter/src/test/java/software/amazon/distro/opentelemetry/exporter/xray/udp/trace/AwsXrayUdpSpanExporterTest.java#L42-L44

PR-1049 fixed the failure in one location but missed another instance. This PR addresses the remaining failure in the test: UdpExporterTest.java
