OTEL without Agent - Transaction lost if not bound to scope

[lbloder]

Integration

sentry-opentelemetry-core

Java Version

17

Version

8.0.0-rc.2

Steps to Reproduce

• Use the sentry-samples-console-opentelemetry-noagent sample or setup OTEL without agent in a simple java console application
• Start and finish a transaction without calling makeCurrent
• To make this more reproducible, also call the garbage collector

ITransaction lostTransaction = Sentry.startTransaction("lost transaction", "op");
System.gc();
lostTransaction.finish();

Expected Result

Transaction is sent to sentry

Actual Result

Transaction is not sent to sentry, because of a WeakReference to an OtelSpan in OtelSpanWrapper, which is garbage collected if not bound to scope
