Example 6 with ChannelOutboundHandlerAdapter

use of io.netty.channel.ChannelOutboundHandlerAdapter in project netty by netty.

the class Http2MultiplexCodecTest method failedOutboundStreamCreationThrowsAndClosesChannel.

/**
     * Test failing the promise of the first headers frame of an outbound stream. In practice this error case would most
     * likely happen due to the max concurrent streams limit being hit or the channel running out of stream identifiers.

    parentChannel.pipeline().addFirst(new ChannelOutboundHandlerAdapter() {
