ObjectStamp cannot be cast IntegerStamp

[dsyer]

I have no idea what this means, or if there is a way for me to configure around it. Here's the error (when generating a native-image):

Caused by: java.lang.ClassCastException: org.graalvm.compiler.core.common.type.ObjectStamp cannot be cast to org.graalvm.compiler.core.common.type.IntegerStamp

This seems to happen when "fixing" sub-word values for primitive return values (getting a reference instead). It could be some ill-formed bytecode... and there's been some related changes lately; Can you please provide more details? Graal version? And if possible a way to reproduce?

[dsyer]

I was using rc2. You can reproduce using the "func" branch here: https://github.com/dsyer/spring-boot-micro-apps/tree/func. Follow the instructions in the README, but use com.example.func.FuncApplication instead of MicroApplication (which works).

Thanks for reporting, a fix is already being reviewed. It won't be out for RC3; you'll have to wait for RC4 or build SVM from source; there's no quick workaround. I'll close this issue when it's merged.
MicroApplication compiles and runs fine.
FuncApplication compiles but fails at runtime, here's the log:

Fixed in fda115b

[dsyer]

This was marked as fixed before rc3 was released. I just tried rc4 and it's still broken even with the MicroApplication. Do we need a new issue, or just some more clarity on when this fix is going to be released?

The func branch of the repo above is up to date, and I split the JSON config into micro.json (works with MicroApplication) and func.json (formerly worked with BuncApplication) when I compiled graal from source before rc4.

So MicroApplication actually does still work, but not if you try and use the wrong JSON (e.g. just switch micro.json for func.json and you get the error above). The FuncApplication and BuncApplication both fail the same way.

[dsyer]

More data: deleting stuff systematically from func.json until it works, it appears that the ClassCastException first appears when you add this to the JSON:

	{
		"name": "org.springframework.boot.web.server.WebServerFactoryCustomizerBeanPostProcessor",
		"methods": [
			{
				"name": "<init>",
				"parameterTypes": []
			}
		]
	}

So in fact, using a JSON file with just that entry is enough to break the compilation in a native-image build. I don't think the code in WebServerFactoryCustomizerBeanPostProcessor has changed lately, so something in graal did change I guess. Hopefully this will make it easier to pinpoint.

[sdeleuze]

@dougxc @mukel Is fda115b part of RC4? If yes, this issue should probably be reopened.

[mukel]

Landed just after the freeze, should be out for RC5.

[dsyer]

How about using the "milestone" feature in Github to track that?
