java.lang.OutOfMemoryError: Direct buffer memory

    When sending fragmented binary message (message with message payload of length 4 * 2**20 (4M). Sent out in fragments of 64). The server throws {{java.lang.OutOfMemoryError: Direct buffer memory}} [1] The memory for direct buffer by default depends on the size set by -Xmx, which is in EAP 7.0.0.DR4 by default set to -Xmx512m. Increasing it just increases the time before the limit is hit (it is enough to send those messages multiple times to hit the limit again). I believe the issue is similar to the one for EAP 6.4: [] [1] {noformat} 15:10:55,463 ERROR [org.xnio.listener] (default I/O-1) XNIO001007: A channel event listener threw an exception: java.lang.OutOfMemoryError: Direct buffer memory at java.nio.Bits.reserveMemory( at java.nio.DirectByteBuffer.<init>( at java.nio.ByteBuffer.allocateDirect( at org.xnio.BufferAllocator$2.allocate( at org.xnio.BufferAllocator$2.allocate( at org.xnio.ByteBufferSlicePool.allocate( at io.undertow.websockets.core.BufferedBinaryMessage$1.handleEvent( at io.undertow.websockets.core.BufferedBinaryMessage$1.handleEvent( at org.xnio.ChannelListeners.invokeChannelListener( at io.undertow.server.protocol.framed.AbstractFramedStreamSourceChannel$ at org.xnio.nio.WorkerThread.safeRun( at {noformat}

    sshandle still have memory leak, tested with 4.0.24, 4.0.25 and 4.0.17.
