When an exception occurs in a static initialization, it is not logged in AppInsights.

Investigative information

Please provide the following:

  • Timestamp: 2019-06-21T17:48:38.384
  • Invocation ID: 48d86a7c24b1354196e9c0c9b6ee7d19
  • Region: Central US

Repro steps

Here's a sample function to reproduce:

package com.yevster;

import java.io.IOException;
import java.net.MalformedURLException;
import java.util.Optional;

import com.microsoft.azure.functions.ExecutionContext;
import com.microsoft.azure.functions.HttpMethod;
import com.microsoft.azure.functions.HttpRequestMessage;
import com.microsoft.azure.functions.HttpResponseMessage;
import com.microsoft.azure.functions.HttpStatus;
import com.microsoft.azure.functions.annotation.AuthorizationLevel;
import com.microsoft.azure.functions.annotation.FunctionName;
import com.microsoft.azure.functions.annotation.HttpTrigger;

public class ProtoFunction {
	static {
		//Puke!
		Optional.empty().orElseThrow(()->new RuntimeException("Life isn't fair!"));
	}
	
	@FunctionName("prototype")
	public HttpResponseMessage run(@HttpTrigger(name = "req", methods = {
			HttpMethod.GET }, authLevel = AuthorizationLevel.ANONYMOUS) HttpRequestMessage<Optional<byte[]>> request,
			final ExecutionContext context) throws MalformedURLException, IOException {
	
		return request.createResponseBuilder(HttpStatus.OK).header("Content-Type", "text/html").body("<html><body><h1>Rejoice! All is well!</h1></body></html>").build();
	}
}

And here's what AppInsights shows when queried for all exceptions and trace messages after invocation of that function:

@amamounelsayed - Check if this happens in other languages. Also, check if this will be part of appInsights work.

I just want to add, that (at least) when using @ServiceBusQueueTrigger, the output will only be that the function timeouted without any reason or hint that a class initialization failed. Support only suggested upgrading function runtime to 4.x (does not help), check logs (nothing to see) and verify Application Insights (nothing to see)
