OTSpanContex.toTraceId() truncates 128-bit TraceIds to 64-bit decimal.

[LeifW]

The toTraceId() method on OTSpanContext calls .toString() on the DDTraceId, which the Javadoc for says "Returns a 64-bit only decimal String representation of the DDTraceId".
So how do we get the original 128-bit hexadecimal TraceId?

Hello @LeifW

You cannot get the 128-bit trace identifier from the OpenTracing API. You will only have the 64 lower bits as an integer.
What is your use case that needs it?
