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.`

#### 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.
