Description

When invoking writePacket, I quite often get the following exception:

Caused by: java.lang.ArrayIndexOutOfBoundsException arraycopy: last source index 32768 out of bounds for byte[8192] 
at java.base/java.lang.System.arraycopy(Native Method) 
at org.apache.sshd.common.util.buffer.ByteArrayBuffer.putRawBytes(ByteArrayBuffer.java:230) 
at org.apache.sshd.common.channel.ChannelAsyncOutputStream.createSendBuffer(ChannelAsyncOutputStream.java:229) 
at org.apache.sshd.common.channel.ChannelAsyncOutputStream.doWriteIfPossible(ChannelAsyncOutputStream.java:164) 
at org.apache.sshd.common.channel.ChannelAsyncOutputStream.writePacket(ChannelAsyncOutputStream.java:70)

This never happened in 2.4.0, so it is definitely a regression
