Typing "/say @e" kicks the client

Whenever I do /say @e on a server, it kicks me and says this:
"Connection Lost"
"Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(1) + length(1) exceeds writerIndex(1): UnpooledHeapByteBuf(ridx: 1, widx: 1, cap:1)"

It also affects Minecraft 1.8.8.
