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.

[georgeOsdDev]

worker.config.json specify -noverify parameter as JVM arguments.

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.

Investigative information

• 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.
