The problem was that on zulu8 loading OkHttp touches JFR which in turn
touches log manager - which would break things like JBOSS.
The fix is to delay installing agent (and writer) until log manager
things have settled down - in way similar to jmxfetch.
Unfortunately for 'main' agent this turns out to be more involved
because of classloader shenanigans.
Unfortunately 404 test was not consistent and non-trivial to adapt. I also couldn’t get the validation tests to work well either. Revisit if we have time to dig deeper into spring.
The core changes are in Config and ServerDecorator.
Moved default tagging from Config::getRuntimeTags to Config::getLocalRootSpanTags. This changes the result of Config::getMergedJmxTags as well.
To preserve language for servers changed ServerDecorator::afterStart.
Other changes are in tests - the most complicated part is in TagsAssert::defaultTags. This now contains a bit too much conditional logic for my liking.
Otherwise it can interfere with the more common Servlet instrumentation (changing the root span name).
Unify attribute/property name for saving span on a request/context.
Also add tests for embedded GlassFish.
(Don’t be surprised when things break with 2.8… They’re religious about removing deprecated methods on minor release versions. If they followed standard convention, they’d likely be on at least 11.x.)
Add client test for 2.4-2.5 http library. 2.6+ won’t work because the underlying frameworks we instrument are shaded.
Also add server tests. We could do a lot more testing since it seems play still supports using Netty as the backing server even though it’s not the default. It’s difficult to do extensive testing though because they have so many breaking changes between versions.
Currently missing the authentication tests which need to be added to the parent, but other than that, testing is more thorough.
Discovered that trace propagation for Jetty Async is currently busted so I commented that portion of the test out until we can get it fixed.
Previously the scope was the http client span, which could result in deep nesting. Now it is the parent span.
Before

Now:

[ ^ —Client—] [ ^—Child—]
Also improve the tests.
