Guava context propagation inconsistent

[anuraaga]

I found a long standing issue in our Guava instrumentation while migrating the tests to Java. It would be good to fix it at some point, filing this issue to make sure it's not lost.

Closing, can revisit later if anyone has renewed interest.

and it's still tracked via TODO:

opentelemetry-java-instrumentation/instrumentation/guava-10.0/javaagent/src/test/java/io/opentelemetry/javaagent/instrumentation/guava/v10_0/ListenableFutureTest.java

Lines 186 to 187 in f30601d

	// TODO: There appears to be a context propagation bug. There is no logical reason for other to
	// be the parent of callback in this test but not in callWithParent.
