Evgeny Pasynkov commented on SSHD-1032:
---------------------------------------
No, this is not related to SFTP code. The server application receives incoming
SSH requests and handles the command execution by itself (Actually, the
commands are domain specific for application).
The provided stacktrace are the only frames involving mina.sshd - all frames
above are from my application. I do the following (Kotlin language):
{code:java}
val buffer = ByteArray(8192)
..... fill buffer with actual data to send.....
IoOutputStream.writePacket(ByteArrayBuffer(buffer, 0, min(length, 8192), true))
{code}
> java.lang.ArrayIndexOutOfBoundsException arraycopy

> Key: SSHD-1032
> URL: https://issues.apache.org/jira/browse/SSHD-1032
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 2.5.0
> Reporter: Evgeny Pasynkov
> Priority: Major
>
> When invoking writePacket, I quite often get the following exception:
> {noformat}
> 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){noformat}
> This never happened in 2.4.0, so it is definitely a regression
