In theory this should be safe as I cannot imagine a situation where a leftover active destruction context would be intentional. It won't be perfect solution, but it is more robust than what we have now.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0"> </p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">An automated test is probably not viable as we would need to "corrupt" all thread in WFLY to be able to reliably achieve the faulty state. Hence I will put together a PR, test that against our TS, then WFLY TS and ask the original reported to verify as well.</p> </td>
