[zhaolianwang]

same problem ^-^

[zhaolianwang]

reason: WebSocketTransport line 144 : Packet packet = new Packet(PacketType.MESSAGE); //subType =null PacketEncoder line 288: byte subType = toChar(packet.getSubType().getValue()); //NullPointerException

fix WebSocketTransport Packet packet = new Packet(PacketType.MESSAGE); packet.setSubType(PacketType.DISCONNECT);

[Ben-Mark]

can someone merge the mem leak fix ?

[wilddylan]

@Ben-Mark code was tested, pull this code to local, modified and publish to your private repo or git for use.

[Ben-Mark]

@WildDylan thank you

@thisdaydayde @mrniko Hello, is there netty-socketio project has any Configuration setLevel for ResourceLeakDetector ?

ResourceLeakDetector.setLevel(ResourceLeakDetector.Level.ADVANCED);

Thanks.
