To be clear, the reasons as to why the original proposal was amended are as follows: * it is a "bug" rather than a feature that exceptions are swallowed by a cleaner. Having those exceptions bubbling up when calling `Arena::close` provides meaningful diagnostic feedback; * the fact that an automatic arena doesn't report any exception from custom cleanup can be seen explained as: a `Cleaner` will call `Arena::close` implicitly, so exceptions (including the new `Arena.CleanupException`) will be swallowed. ------------- PR Comment: https://git.openjdk.org/jdk/pull/16619#issuecomment-1808531110
