Hi, Please find a small fix for:
8177935: java/net/httpclient/http2/FixedThreadPoolTest.java fails frequently https://bugs.openjdk.java.net/browse/JDK-8177935 webrev: http://cr.openjdk.java.net/~dfuchs/webrev_8177935/webrev/ The "Should not happen" exception happens because of a race condition in AsyncWriteQueue which may occur between consumeAction.accept(...) and state.get() (between lines 159 and 160 in the original file). There is a small window of opportunity here, where the WriteEvent registered by consumeAction.accept() may already have been triggered and entered the flushLoop() and switched the state to FLUSHING before the already running flushLoop() had a chance to observe the DELAYED state and running. This will cause two flushLoop() to run concurrently in the critical section, and this can cause anything to happen. The solution is to change the consumeAction() to return a boolean (false) if it wasn't able to flush all the data. best regards, -- daniel
