Unexpected JDK warning message: OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.

worker.config.json specify -noverify parameter as JVM arguments. https://github.com/Azure/azure-functions-java-worker/blob/687d37389b8c2fc82259a39cecf94a2bfae23ed8/worker.config.json

This option make noisy records on traces table with warning level. OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.

Timestamp: N/A
Function App name: N/A
Function name(s) (as appropriate): N/A
Invocation ID: N/A
Region: N/A

Repro steps

Check traces log on startup

Expected behavior

Disable JDK warning message(s)

Actual behavior

There are 2 JDK warnings on start up

OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.
OpenJDK 64-Bit Server VM warning: Sharing is only supported for boot loader classes because bootstrap classpath has been appended

I think first message can be disabled by removing -noverify JVM arguments. But there is no configurable way for Azure Functions Java Worker.

Known workarounds

I think we can ignore this message by configuring logLevel of Host.Function.Console category.
