Vertex integration throw NullPointerException due to null span

[miladjafary]

Hi I have used the dd-trace-java agent to trace my service which is develop on top of Quarkus framework. However when DataDog agent wants to trace a vertx request generate the following error which say the span is null.

Could you help me out how could I resolve it? I use the latest version of trace which I download it from https://dtdg.co/latest-java-tracer

java.lang.NullPointerException: Cannot invoke "datadog.trace.bootstrap.instrumentation.api.AgentSpan.setTag(String, java.lang.CharSequence)" because "span" is null

Hi @smola is there any workaround to solve this problem?

[bm1549]

Can you confirm if the fix in #5203 resolves your issue?

It was released as part of v1.15.0, but ideally you should use the latest release of v.1.21.0

@bm1549 I've used the version 1.24.2 and I confirmed it has been fixed
