### Events with Failures

When an operation fails, a failure method is called. This is `connectFailed()` for failures while building a connection to the server, and `callFailed()` when the HTTP call fails permanently. When a failure happens it is possible that a `start` event won’t have a corresponding `end` event.

## Building and Testing

The most reliable way to build and test Guava is:

```shell
./mvnw clean install
```

If you want to run a single test, you'll need to pass multiple flags because

import org.eclipse.aether.resolution.ArtifactRequest;
import org.eclipse.aether.util.artifact.ArtifactIdUtils;

import static java.util.Objects.requireNonNull;

/**
 * A class building reverse tree using {@link CollectStepData} trace data provided in {@link RepositoryEvent}
 * events fired during collection.
 *
 * @since 3.9.0
 */
class ReverseTreeRepositoryListener extends AbstractRepositoryListener {

    /**
     * Sets up the query conditions for retrieving job logs based on the pager configuration.
     * Configures filtering and ordering for the database query.
     *
     * @param cb the condition bean for building the query
     * @param jobLogPager the pager containing filter and search criteria
     */
    protected void setupListCondition(final JobLogCB cb, final JobLogPager jobLogPager) {
        if (jobLogPager.id != null) {

    This could have corrupted requests where multiple headers had the same name,
    as in cookies.
 *  Fix: Reject bad characters in the URL hostname. Previously characters like
    `\0` would cause a late crash when building the request.
 *  Fix: Allow interceptors to change the request method.
 *  Fix: Don’t use the request's `User-Agent` or `Proxy-Authorization` when
    connecting to an HTTPS server via an HTTP tunnel. The `Proxy-Authorization`
