TRACE log level causes an application to fail

Bắt đầu bằng stack trace và đọc AppInsightsCertificate.java, đặc biệt là executeWithoutException, loadCertificates và isInJavaKeystore, sau đó kiểm tra FirstEntryPoint.init. Tái hiện quá trình khởi động agent với TRACE khi keytool không khả dụng và xác định lý do điều này khiến ứng dụng bị lỗi. Hoàn thành khi ứng dụng khởi động thành công và điều kiện thiếu keytool được ghi log mà không hủy quá trình khởi động.

Expected behavior

Don't fail a main application. Probably use WARN log level.

Actual behavior

The enabled JVM agent with TRACE log level causes a Java application to fail.

To Reproduce

1. Connect a JVM agent (-javagent:/path/to/application-insights-3.4.17.jar).
2. Provide a connection string.
3. Set an environment variable APPLICATIONINSIGHTS_SELF_DIAGNOSTICS_LEVEL to TRACE.
4. Run a Java application.

System information

Please provide the following information:

• SDK Version: 3.4.17
• OS type and version: RHEL 8.9
• Application Server type and version (if applicable): Apache Spark 3.4.
• Using spring-boot? No.
• Additional relevant libraries (with version, if applicable): N/A.
