Initial naive attempt clearly doesn't pass. |

Replaced original attempt (clear interrupt queue when raising) with a new version that simply avoids polling during IO for the raise report. This should fix the original issue without substantially changing the way interrupts are handled. |

Dynamically printing error output to the configured stderr stream may trigger additional thread interrupt polls, wiping out any thread interrupt currently being reported or propagated. This patch avoids such polls by writing directly to the underlying IO without using Ruby logic if and only if it is the original (boot) stderr stream. This also removes a second poll that happens when exiting the blocking task for a raise, a side effect of using afterBlockingCall to set the new status. The status update happens again after this point, and the poll is spurious. Fixes jruby#8479

Avoid polling during propagation and report of a
Thread#raiseexception. If we dispatch dynamically to the configured stderr, we may hit additional polls that trigger new interrupts, wiping out the raise interrupt currently being handled.Fixes #8479
