gosh_profile errors on startup of substrate

If I try to configure a custom gosh_profile and motd with the created substrate I get the following error:

```
/gosh_profile: ERROR: java.lang.IllegalArgumentException: Cannot coerce resolve(Token) to any of []
```

With the Atomos substrate examples the error looks a bit different, but almost the same:

```
gosh_profile: ERROR: java.lang.IllegalArgumentException: Cannot coerce addcommand(Token, BundleContextImpl) to any of []
```

Somehow the `gosh_profile` execution does not work correctly.
I tried several things to make it work, but I don't get the point what is missing in the reflection configuration. Even using the java_agent and inspecting the resulting configs did not uncover anything related to this specific thing. Any ideas what could be missing?

Reproduce the startup failure with a custom gosh_profile and motd on the created substrate, then compare it with the Atomos substrate examples. Start by investigating the reflection configuration using the java_agent and the reported resolve(Token) and addcommand(Token, BundleContextImpl) coercion errors. Done means gosh_profile executes successfully without these startup errors.
