Research direction

Start by reading androidx.test.services.events.internal.Throwables.getCauseStackTraceLines at Throwables.java:70, then trace its callers through getTrimmedStackTrace, StackTrimmer.getTrimmedStackTrace, and ParcelableConverter.getFailure. Reproduce the failure from the supplied stack trace on API 28 and verify that generating a test failure report no longer throws StringIndexOutOfBoundsException.
