TRACE log level causes an application to fail

Inizia dallo stack trace e leggi AppInsightsCertificate.java, in particolare executeWithoutException, loadCertificates e isInJavaKeystore, quindi esamina FirstEntryPoint.init. Riproduci l’avvio dell’agente con TRACE quando keytool non è disponibile e determina perché questo causa il fallimento dell’applicazione. Il lavoro è completato quando l’applicazione si avvia correttamente e la condizione di keytool mancante viene registrata senza interrompere l’avvio.

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.
