JDK-6986483 - CHA: optimize calls through interfaces
Description
Jtreg hotspot test compiler/cha/StrengthReduceInterfaceCall.java fails in the Valhalla nestmates repo with the following error:

Caused by: java.lang.IncompatibleClassChangeError: Type compiler.cha.StrengthReduceInterfaceCall$ObjectToString (loader: compiler.cha.StrengthReduceInterfaceCall$MyClassLoader @5e8ad876) is not a nest member of compiler.cha.StrengthReduceInterfaceCall (loader: 'app'): types are in different packages
Comments
The test no longer fails.

The test is new. It was added on 31-Jan-2019 as part of the fix for JDK-6986483.

Types loaded by different classloaders are by definition in different runtime packages. Has something changed to make this test fail? Is it new? We've had a few tests where nested types were explicitly loaded in a different classloader, but this seems a new one.

It looks like the ICCE is thrown because the nest member check fails. It fails because even though the two classes are in the same package they have different class loaders.
