setRoomVariables issues "Deflater has been closed"
Posted: 31 Aug 2018, 04:14
Our user report unexpected disconnection. I found some exception ejected when users occur unexpected disconnection.
This exceptions refer to my code setRoomVariables;
I have weird logic around my program before "setRoomVariable"
I checked new SfsObject whether is equal with previous state of SfsObject.
If iSfsObject is changed, update my RoomVariable with this SfsObject
I have no ideal. How do I resolve these issue?
Thank you.

I checked new SfsObject whether is equal with previous state of SfsObject.
If iSfsObject is changed, update my RoomVariable with this SfsObject
Code: Select all
RoomVariable variable1 = room.getVariable(betPoolKey);
ISFSObject oldValue = variable1.getSFSObjectValue();
byte[] oldByteValue = oldValue.toBinary();
byte[] newByteValue = newBetPoolData.toBinary();
boolean equals = Arrays.equals(oldByteValue, newByteValue);
Thank you.
