Route must have a low cardinality. Often it is not possible to get route for a low level server framework. Just return null here.

[SentryMan]

I don't follow, exchange.getHttpContext().getPath() gives you the configured path for the route, not what is currently matched

[SentryMan]

that is, if you do

    HttpServer server = HttpServer.create(new InetSocketAddress(port), 0);
    server.createContext("/path/" ctx ->{});

and send a request to /path/something, you'll get /path/ from exchange.getHttpContext().getPath()

@laurit perchance do you know why it's failing now?

@laurit perchance do you know why it's failing now?

I haven't followed the discussions above, but looks like its:

2025-02-07T18:19:27.2764194Z > Task :instrumentation:java-http-server:javaagent:test
2025-02-07T18:19:27.2766261Z 
2025-02-07T18:19:27.2768473Z JdkHttpServerTest > httpPipelining() FAILED

you could opt-out of the http pipelining test initially at least, look for options.setTestHttpPipelining(false)

[SentryMan]

what's the best way to search these error logs, I'm having trouble locating the actual tests that are failing.

So I add a Readme and the pipeline fails?

So I add a Readme and the pipeline fails?

we have been doing some compliance work in the repo recently which introduced a couple of new required PR checks, and so just need to rebase to main to fix (looks like @laurit has done that)

thanks @SentryMan @laurit! one suggestion on the package name
