Java compiler crash when using non-existent inner class

I get a compiler crash when running javac -processor TaintingChecker Outer.java.

import org.checkerframework.checker.tainting.qual.*;

public class Outer {
    public void f(@Untainted Outer. @Untainted Inner param) {
    }
}

An exception has occurred in the compiler (11.0.8). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report. Thank you.

This crash doesn't occur with regular javac when passing -cp $CHECKERFRAMEWORK/checker/dist/checker-qual.jar. It also doesn't occur when I remove -processor TaintingChecker. This might indicate the framework is side-effecting the javac constructs somehow. Also, the crash doesn't happen when the class Inner actually exists.

Output of javac -processor TaintingChecker Outer.java -version -verbose -AprintAllQualifiers:
javac_output.txt

Reproduce the crash with the supplied Outer.java example using javac -processor TaintingChecker, then compare it with regular javac and with Inner defined. Start from the TypeAnnotations and ErrorType frames in the javac stack trace; done means the non-existent inner-class case no longer crashes the compiler while the relevant compilation behavior remains covered.
