According to my researches this issue is not the same as existing ones even if the error message is the same (#22532, #22244 …)

Current behavior

When project is run with ng serve --aot I have the following error in the browser :

09:32:05.275 main.ts:9 pre-test
09:32:05.277 test.1.ts:46 step 1
09:32:05.278 core.js:1926 Uncaught Error: Cannot resolve all parameters for 'CustomProvider'(?). Make sure that all the parameters are decorated with Inject or have valid type annotations and that 'CustomProvider' is decorated with Injectable.

Expected behavior

I should have the same output I have in JIT

Minimal reproduction of the problem with instructions

I have attached a demo project. In order to create this project I used ng cli to bootstrap the project, then added files test.1.ts and test.2.ts. And an simple call to test() function from main.ts

test3.zip

What is the motivation / use case for changing the behavior?

@no-more … nobody will download a foreign ZIP file. So still create that Plunker demo even if the error wouldn’t be seen, because of the source code shows the mistake. From 99,9% it’s your mistake.

Thanks but I don’t know how to create a plunker with AOT. Plunker is great tool for code issue, here I think the issue might be related to the compiler (ngc + aot in this case).
