Assertion error in TypeAnnotations$TypeAnnotationPositions.resolveFrame

ADDITIONAL SYSTEM INFORMATION :
The test for v11.0.1 and v1.8.0_191 were done using the Oracle JDK, those for 10.0.2 and 11.0.1 using the OpenJDK, but given the results I don’t think there is a distinction between the two.

A DESCRIPTION OF THE PROBLEM :
Attempting to compile the code attached below leads to an Assertion error. I could reproduce it with Java versions 12-ea19, 11.0.1 and 10.0.2 but not with 1.8.0_191.

REGRESSION : Last worked in version 8u191

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Save the attached source code as TestBug.java and attempt to compile it with “javac TestBug.java”

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The file should be compiled into a .class file.
ACTUAL -
$ javac -version
javac 11.0.1
$ javac TestBug.java
An exception has occurred in the compiler (11.0.1). 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.

CUSTOMER SUBMITTED WORKAROUND :
The bug appears to be quite specific to the code structure, I have not been able to simplify the test code more than this. In my case this appeared in a much more complicated class; Consumer, Function and TestAnnotation were all custom classes and interfaces. In general, refactoring the code can avoid the error. (In my case, I moved the buggy declaration outside the Runnable.)

FREQUENCY : always
