I am using the EagerFormParsingHandler.
In my subsequent handler I am using
HttpServerExchange.dispatch(Runnable)
in order to delegate my work to a worker thread.
However, since FormEncodedDataDefinition dispatches to the subsequent handler using a SameThreadExecutor, that same executor is the 'dispatchExecutor' on the request and the worker thread pool is not used in my handler.
The call stack when this occurs looks like this:
<my handler here> io.undertow.util.SameThreadExecutor.execute (SameThreadExecutor.java:35, bci=1, compiled) io.undertow.server.Connectors.executeRootHandler (Connectors.java:228, bci=105, compiled) io.undertow.server.HttpServerExchange$1.run (HttpServerExchange.java:809, bci=8, compiled) io.undertow.util.SameThreadExecutor.execute (SameThreadExecutor.java:35, bci=1, compiled) io.undertow.server.HttpServerExchange.dispatch (HttpServerExchange.java:794, bci=76, compiled) io.undertow.server.HttpServerExchange.dispatch (HttpServerExchange.java:812, bci=13, compiled) io.undertow.server.handlers.form.FormEncodedDataDefinition$FormEncodedDataParser.handleEvent (FormEncodedDataDefinition.java:117, bci=24, compiled) io.undertow.server.handlers.form.FormEncodedDataDefinition$FormEncodedDataParser.handleEvent (FormEncodedDataDefinition.java:90, bci=5, compiled) org.xnio.ChannelListeners.invokeChannelListener (ChannelListeners.java:92, bci=18, compiled) io.undertow.channels.DetachableStreamSourceChannel$SetterDelegatingListener.handleEvent (DetachableStreamSourceChannel.java:231, bci=17, compiled) io.undertow.channels.DetachableStreamSourceChannel$SetterDelegatingListener.handleEvent (DetachableStreamSourceChannel.java:218, bci=5, compiled) org.xnio.ChannelListeners.invokeChannelListener (ChannelListeners.java:92, bci=18, compiled) org.xnio.conduits.ReadReadyHandler$ChannelListenerHandler.readReady (ReadReadyHandler.java:66, bci=34, compiled) org.xnio.nio.NioSocketConduit.handleReady (NioSocketConduit.java:88, bci=51, compiled) org.xnio.nio.WorkerThread.run (WorkerThread.java:559, bci=842, compiled)
This caused unexpected blockage of an IO thread since HttpServerExchange#dispatch(Runnable) states that it will occur on the worker thread pool, but that's not what actually happened.
