📜 Description

Moves sentry-samples-log4j2's system test into sentry-log4j2 as SentryAppenderIntegrationTest, the log4j2 version of the logback test in #6268. The sample's test ran its JAR against the Python mock server. The new test configures the Sentry appender from XML in-process and checks what reaches MockSentryServer:

• the warning event, with its userId context tag and feature flag;
• the error, with its RuntimeException and the debug and info breadcrumbs;
• the logs, with the scope's attributes.

Two details:

• XML configuration: the config is a non-default resource, sentry-appender-integration-test.xml, so it covers how log4j2.xml binds the appender's attributes. The DSN reaches it through a ${sys:...} lookup. The test builds a LoggerContext of its own from the file, so SentryAppenderTest's context keeps its configuration.
• Logs: the appender has no attribute to enable them. The sample enabled them in sentry.properties, so the test uses the same external-configuration path, through the sentry.logs.enabled system property.

With no system tests left, the sample comes off the runner and the backend workflow. It also drops the Kotlin plugin, which only the test needed. sentry-log4j2 gets Truth as a test dependency.

💡 Motivation and Context

The log4j2 appender's XML binding now runs in ./gradlew :sentry-log4j2:test, in about 0.2 seconds.

💚 How did you test it?

• The test passes, and so do the module's other 33 tests next to it.
• Expecting a different warning message makes it fail.
• :sentry-log4j2:check passes, and the sample's JAR still builds.

📝 Checklist

• I added GH Issue ID & Linear ID
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.
• Public API changes reviewed by another Mobile SDK team member or implemented according to the develop docs spec.

🔮 Next steps

The JUL sample, then the plain console sample.
