Hi. The error only happens when dd-java-agent.jar is used, e.g. via:

LUCEE_JAVA_OPTS=-javaagent:/cfcustom/agents/dd-java-agent.jar -Ddd.trace.otel.enabled=true

Otherwise opentelemetry runs fine on all versions

Also the below runs okay:

<cfset createObject("java", "io.opentelemetry.api.trace.Span").current()>

The error only happens when cfdump is used:

<cfdump var="#createObject("java", "io.opentelemetry.api.trace.Span").current()#">

Alternatively, the error also happens when using the below:

<cfset LOCAL.span = createObject("java", "io.opentelemetry.api.trace.Span").current()>
<cfset LOCAL.span.setAttribute("hello", "world")>

Looks good 👍
