### Version 2.12.1 ### Bug description Hi everyone, I'm currently using sshd-core version 2.12.1 in a Maven-based Java project. I wanted to upgrade to a more recent version (e.g., 2.15.0), but unfortunately, I encountered a critical issue when downloading large files via SFTP. When I attempt to download a large file using SftpInputStreamAsync, I receive the following exception: ` java.lang.NullPointerException: Cannot invoke "org.apache.sshd.common.util.buffer.Buffer.available()" because "this.buffer" is null at org.apache.sshd.sftp.client.impl.SftpInputStreamAsync.sendRequests(SftpInputStreamAsync.java:245) at org.apache.sshd.sftp.client.impl.SftpInputStreamAsync.doRead(SftpInputStreamAsync.java:195) at org.apache.sshd.sftp.client.impl.SftpInputStreamAsync.transferTo(SftpInputStreamAsync.java:152) ` This behavior does not occur in version 2.12.1, so I suspect it's a regression introduced in 2.13.1 or later. - Is this a known issue? - Is there a recommended workaround for downloading large files with newer versions? Thanks a lot for your support and for maintaining this project! ### Actual behavior . ### Expected behavior . ### Relevant log output ```Shell ``` ### Other information _No response_ -- This is an automated message from the Apache Git Service.
