Motivation: We need to ensure we override fillInStacktrace() when we store exceptions in static fields to not leak the Classloader in the backtrace. Came up in https://github.com/netty/netty/pull/10691#issuecomment-738331186. Thanks to @amir-shalem for notice this one. Modifications: - Add overrides of fillInStracktrace in TrackRecord.BOTTOM Result: Related fix to https://github.com/netty/netty/pull/10686
