Expectation

The nullness checker should not crash on this file. I have verified that this crash does not occur using 3.15.0. I have no deep insights into what specifically might be causing the crash, but I minimized the input as much as I could. In particular, surprisingly, even the empty Super class is necessary: if Issue extends Template<String> directly, the checker succeeds.

I confirm that the Checker Framework crashes on this code. Thank you for providing a minimized, reproducible bug report -- we appreciate it.

I have committed a test case as checker/tests/nullness/Issue4924.java.
